Have you deleted the poser.ini file from your ?... My Documents Folder I think? There's a user data folder sort of .Poser?8/poser.ini you can search for If thats corrupt you will experience that kind of stuff. I would suppose that 32bit install of Pro 2010 would use that Folder (I don't have Pro 2010 to check)

A word is not the same with one writer as with another. One tears it from his guts. The other pulls it out of his overcoat pocket
Charles Péguy

 Heat and animosity, contest and conflict, may sharpen the wits, although they rarely do;they never strengthen the understanding, clear the perspicacity, guide the judgment, or improve the heart
Walter Savage Landor

So is that TTFN or TANSTAAFL?
