Perhaps you will find out in the previous posts but what's happening is the pz2, cr2, hr2, pp2 (pose, character, hair and prop) files in your folders have texture map references whose paths are incorrect. Without Pbooost, this doesn't matter. Poser will load called for textures as long as it finds them anywhere on the machine and regardless of the path used in the file. With PBooost, the references have to be correct. The MAT pose file (or any of the others I listed) cannot call for "C:posermapmytexture.jpg" if the file is actually in "runtime:textures:ken:mytexture.jpg". So what has to be done (and it's a JOB) is that all your files which call textures have to be adjusted with the Deep File Editor (comes with PB) or CorrectReference, a separate program also from Hogsoft. That's the bare bones explanation. Once the references are correct, you'll be able to switch banks without the program finding the conflict and locking. This, by the way, is apparently a problem with how Poser proprieterizes the windows file/folder system.

WHEW! : )
