This seemed to be the case when i had the BOSD.

The problem that occurs is when you have the proection to the on setting within the program and you switch passwords or you delete the protected/watched folder without first disableling the protection. It Give an Exception on the xlkfs.sys

So, when you start chenging settings to file and folders, be sure to disable the protection first.

Sinds then i dit not had any problems with the file locker again.

Hope this works for you too.
