Hi
A couple of FYI's:
Passwords
MYOB never adds a password to a file. Every company file has a user called Administrator and by default the password is blank. If an Administrator password has been set up by the Administrator, it can only be reset by MYOB. However if another user has been added, their password (if any) can be reset by the Administrator.
File Names.
Glad you found the "correct" file. You may need to consider how you use MYOB company file names. Many users (myself included) include the word 'current' in the file name, for example ABCCurrent.myo. If you ever make a copy of this file, call the copy something different. If you restore a backup, call the file something different. This ensures you only ever have one file called ABCCurrent and use this for all transactions. Having several copies of the company file with unclear file names leads to problems for many users. They can't find transactions they entered a few days ago, etc etc because they used the wrong file.
When you say you found the file under a different name and had to Confirm online (you referred to online verification but I assume you were referring to online Confirmation) I would suggest you check the transactions in that file to ensure it includes your recent transactions, and it is in fact your latest file. Being prompted to confirm a file you just opened (and given 14 days to do so) is often but not always a sign this company file has not been opened for awhile. I just hope the file you are now using is your latest file.
