I still have version 6.3 and, even if I wanted, I cannot buy the version 7, as nothing about Blacksmith3d is available anymore. 

I agree totally with Hborre, same issue with digital entertainments like videogames, the server goes POOF and we, the customers, are left with nothing at all. We pay for the use of something for as long as they let us use it, it seems.

Great idea Marciushess, why don't they simply remove the need to access a dead server? I think would be the easiest solution.

Also, thank you ChangelingChick, is there a way to get the version 7 somehow?
