You lost data not because someone was making a copy of your data, but ratter the error message you got.
As per how to fix it, dial customer support (
sorry I cannt help you with that, maybe someone)

BTW: There is a utility called "C:\Program Files (x86)\Pervasive Software\PSQL\bin\W3MONV75.exe"
It will tell you if someone is using your DBA Data. If that is the case you shouldn't copy or backup anything.
