I've been working on a large scale animated short for the last three weeks and things have been going well - until tonight.  Poser Pro 2012 has suddenly gone south and I can't figure out how to solve the problem.

I've been animating a chase in space using the Y2K from 2Mylent and the IanMPalmer Mosquito - two very nice models.  No problems for three weeks.  I've animated over two dozen scenes and Poser Pro 2012 has performed flawlessly.  Tonight I opened a project file.  I could manipulate everything in the scene, the cameras, the lights, the Mosquito, but if I tried anything with the Y2k I got the spinning orb and then the white screen of death.  After a least a dozen tries, shutting everything down (computer and Poser) and firing it back up again, starting a new project, loading the Y2k into a new runtime - always the same result.  Only the Y2K would lock things up, everything else still worked fine.

I reinstalled poser pro 2012 just before I started this project and updated it with SR2.1 and it's been working perfectly.  I know the Y2K is a large file with lots of detail, but I'm running a very fast i7 computer with 24 gigs of ram and it hasn't had a problem until tonight.  Could the file have somehow been corrupted?  I find that hard to beleive since I created a new runtime and it still has the same problem.  Should I remove all traces of the current Y2K in my runtimes, download the file again from Renderosity and reinstall it into the runtime?  I hate to do this as it will probably destroy all the current files I have spent the last three weeks working on, and I am still tweaking the animation for many of them. 

I'm on a tight deadline and can't believe this has suddenly reared its ugly head.  Any help would be most appreciated.
