Problems with ASAM Install

I've recently (last week) tried to install 7801 with ASAM and eventually had to back it out. Here is the synopsis of what happend.

Downloaded 7801.exe
Confirmed we're running v7600
Shutdown the Netflow service
copied both data and mySql folders to another location (overlooked renaming the log folder)
ran the update manager and selected 7801
Update completed without problems
restarted Netflow service
logged into netflow and appeared to be operating normally w/the ASAM
Added some administrator level users
Eventually received call from long term Netflow user that data was missing
backed out the update 7801
copied old MySql and Data folders to original location

Now if I add new users to Netflow they cannot log in... get the message incorrect user id or password which leads me to believe there may be other problems with the DB.

Your insights are appreciated.
