I have watched all of the videos Mark Bremmer did on this subject and have copied the steps to the letter, but when i hit drape Carrara doesnt do anything, it seems like the hair is about to fall then nothing. 

Steps i followed 

drag hair onto object (in this case a figure) 
painted the area i wanted the hair to be on 
added guide hairs 
clicked drape 

but nothing, is there any other step or trick i need to do, i cant even do the above in C8 beta as i get an I/O error (get a lot of them in C8 )

Take a lok at how many division the hair have...

 I have tried with the default of 4 segments per hair and a hair count of  5000 and tried 25 segments per hair and a hair count of 20000 - that's under  - Hair (Per Hair Group), the section underneath - Guide Hairs (Per Hair Group) is greyed out.

Even if i enable that setting it doesn't seem to want to work under Carrara 7 Pro, yet under Carrara 8 beta i can see the guide hairs move a little bit.

All the settings are default ones, thought i best mess about with the hair first then get more into the sliders later

EDIT: just did it on a vertex object and it worked, so any idea's why it wont work if i select a character?

I remember theres a collision distance... maybe its set to high?

 The default under C7 is set to 0.01ft, same for C8 but its not ticked on either,  ticked it but it didn't help.

are you sure the hair is compatible?

 dynamic hair should be, its not one i bought its some i am adding to the character

Aren't there some dynamics under the general tab? If the hair is set too stiff, I think it poofs more than drapes...  Or did the tutorial cover that?

 i lowered all settings and nothing worked, yet the default settings did work if i did a fresh scene using a vertex sphere, i'm wondering if it could have been because i used morphs on the V4 figure before i did the hair, or maybe i need to use a hair cap.

I have only just started looking into dynamic hair so its all a bit new to me still :-)

 I know it works. :-) 

There probably is something that is just getting overlooked. Are you working on a sphere or a full character? If it's a sphere our basic object, feel free to upload the file and I'll take a look. If you are working on a character, please don't upload that since it's protected content. But do try the same steps on another object. 

BTW, there is a C8 update newly available that addresses some regression bugs in the original C8 release. For those that have the full product, you can find the update in your DAZ account area. 

 When i use a sphere it works fine, if i use a default character say M4 or V4 it doesn't, and that's with the same default settings, both C7 and C8 give me this issue, haven't tried it on a mac yet.

As for the C8 update is there one newer than .145 ? If so i best go get it :-)

 Bit of a bump on this but have had some time to explore this issue and i have found the issue, if i double click V4 or any character to load them into the scene i cant get the hair to drape, if i drag them it works.

A strange issue and i would think that it should work reguardless of how you load your figure/prop into a scene, i would report this on the bug tracker but somehow i get the feeling they will just say that draging an object to the menu on the right or into the scene window is the preferd way of adding things to the scene

 Thanks for the update. I always drag mine in so I didn't catch this one. (this issue is similar to some props not getting added when double clicked too) I'll file this with as a bug.

Reported it to bug tracker :-)

I thought how you loaded a character changed it's mesh perameters...meaning if you drag it it loads as a vertex object that can be edited and if you double-click it loads as a mesh. I seem to recall there was a difference in the way you could load objects and whatnot.

 I posted on Daz bug tracker and they have confirmed that it should work no matter which way you load it

OK, good thing to note then.
