" Pboost telling me I couldn't swap files as another program was using them (even though only Poser was running)so I couldn't access any folders. " What Pboost is telling you that there is a bad file reference. Usaully the texture path, Pboost is very sensitive to correct path structure. You can have one file that may have textureMap ":gold.jpg lock you out. Suggest getting CRPro , from Hogsoft, and using it to correct all the references. Second suggestion is to get P3Do Explorer from http://www.senosoft.com, if you don't have it, it's a visual windows explorer. It should display the png and rsr if they are there. Suggestion three, after you've cleaned up your runtime, including what you have in the Pboost banks, always run CRPro against anything you have just installed.

I must remember to remember what it was I had to remember.
