All new databases have the "Admin" as the account name, and a blank password. So try that. However, you should, if you could, use that file only to get the data to Import into an older file before the accident.
Try an account name of 'admin' and leave the password box empty.
If that works, go to File Options and reset the option to log in with those default cresentials
thank you for your quick reply. I did try that but it's stuck. I just can't open the file. It's so stupid, because, just like in your case: I created the database myself. A lot of work... Still searching though for a solution...
What do you mean by "it's stuck"?
Please note that if your database was damaged, it may still be damaged even though you have recovered it.
