I have Bearshare 5.2.5 and about 2 weeks ago it stopped working. Whenever I try to run BS, it pops open for a few seconds (never connects) and I get a pop up that says the following:

/GLibraryWatchDb.cpp (#170) FAtal Error.
Unable to load library database
File exisits: Database file corrupt: stale journal.

I have no idea how to fix this or if it is even fixable. All help is appreciated.

Go into C:\Program Files\BearShare\db and delete the old library files (library.db and library2.db),
rename the obvious backups to replace them and start BearShare again.
If it still doesn't work delete all four files.

First go to folder options and make it so you can see all hidden files and folders then go and look for the following directory. C:\Users\(UserNAME)\AppData\Local\VirtualStore\Pro gram Files\Bearshare\db\ <- this is for vista on XP i guess its similar to that if you cant find it just use the search option on the start menu and type Bearshare, onece i found it i just deleted all files on the db folder and bearshare worked again.
