This works in P4. Never tried it in P5, but it should work. BTW, this fix was posted by SWAMP. It's not something I invented. Oh, and it's better if you can do this with a clean install. 1. In the main poser folder (ie. the one above Runtime), make a copy of all system files (not readmes and other crap). Your Poser.rsr should always be set to 'read only'. If it isn't, change it (in properties). That's the file that continually corrupts when poser crashes. 2. Paste the copied files to a folder called 'Q fix' 3. The next time poser starts acting up, copy all the files from Q fix, and paste them into the main poser folder. This works for me in P4 every time. Once every few months, poser starts this 'insufficient blah, blah'. I just close poser, re-install the files, and when I open it, it's fine again. mac
