I hope I'm remembering this write it's been a while(please forgive me if I'm wrong)... m( _ _)m

I don't think I was using Transposer when that happened to me but it sounds like the same kind of problem I encountered once early on when I first got Carrara5Pro. Characters would not load geometries and textures with out putting me through that search for them every time.

I then by sheer luck had one character load without all the needed searching so I opened it's Cr2 and compared it to the others and what I found is that Poser wrote the paths differently in each.
Poser wrote one with  " : " and the other " ". One worked and the other gave C5P indigestion. When I changed them in the troubled Cr2's the loading troubles went away.

Now the only problem is that I can't remember which of the two " : " or " " was the one C5P liked at the time. It's been a long time since then.

I don't  know if this helps at all because your problem may be something entirely different but I thought I'd throw this in here just in case. Good luck.

Edit. Forum keeps losing the back slashes when I upload. Errgh.
