This is a little thing, but I thought it was worth bringing to your attention. When I used the save configuration option off the FILE menu, the ending message read as follows:
To reestablish your settings extract the file to "C:\Documents and Settings\djRickMitchell.DJRICKMITCHELL\Application Data\Mp3tag" and execute "Mp3tag.reg".
The Mp3tag.reg file is actually one hierarchy beyond the above location at:
"C:\Documents and Settings\djRickMitchell.DJRICKMITCHELL\Application Data\Mp3tag\Data"
Isn't that where you would want to extract it - overwriting the one that is there?
