So you believe somehow that the poser upgrade went into your poser 7 files and deleted them or altered them? Are you sure you didn't file them somewhere else? Have you upgraded your hardware since poser 7 days, and the files weren't elsewhere on your machine and never transferred? You say they are not in poser 7 anymore, this really suggests that poser 11 upgrade has nothing to do with this. If you are talking about basic poser content so for content that was in poser 7 and is still in poser 11, such as Sydney poser may well have installed new versions, but these would be in the poser 11 content folder, and the old ones you installed elsewhere are still likely to be there. For example all my poser 10 content was unaffected.
