I had some weird errors too. I didn't exactely LOOSE the banks but I had to manually rename them to get them back in a working condition. Can't remember which ones they were, but it had me in cold sweat for a moment there L I've also had a neverending cascade of error messages popping up a few times. ctrl-alt-del to kill Pbooost removed them. They have happened when I was trying to move more than one item at a time between banks. I spent the whole afternoon/evening/night 2 days ago running Correct Reference, yet first loaded file yesterday gave me a folder lock. BUT It WAS a pz3, stored outside of where CR fixed things, so that's prolly the reason. All in all I couldn't live without Pbooost, but it has some issues. Some of them probably WinXP related. Yes, I'm using WinXP Home too. On NTFS drives.
