Locked Out of My Database

I have just logged out of my main DB to have a look at some examples but when I went to re-log-in I was asked for a user/password

I do not recall putting a password on the DB. I don’t password anything unless it is very personal as I am the only person on my comp and the DB contains no sensitive or private data as yet …

The only thing I have done this evening is to install & run some scripts and also to disassociate one script from a file (I wasn’t sure if it was a script that came with DTP or if I had put it there)

I am only learning this program so all is certainly not lost but I would like to access the DB I was setting up as I had set prefs and scripts and folders to my liking and was just starting to get the hang

Has any other (idiot) person who has done this to themself??
