Sorry - I missed this part of your posting, in the midst of the detail. You need to be able to log in to your original account (presumably, it's "flip").
OK - so log in as some other user with Administrative privileges, and change the password on "flip" to something else.
It's Control Panel\All Control Panel Items\User Accounts\Manage Another User
Feel free to use the correct one that you remember. [Note: case is important - make sure the shift key is as you want it]
Then log out, and log in as "flip". See if the icon and your MA3 settings are back.
