So if you try to open %APPDATA%\Mp3tag via 'Start > Run...' the folder is not available? I'm asking because %APPDATA% is a hidden directory on most systems.
I have hidden files and folders showing. I looked in a folder called 'Application Data' under Documents and Settings[user] for my user, administrator, all users, and default user. I also tried typing '%APPDATA%\Mp3tag' in Run but it just gives me a message that windows cannot find 'C:\Documents'.
OK, I tried that and it didn't work. I also tried uninstalling and reinstalling and then when I tried to open it gave me the 'The program has encountered an unexpected error' dialog box. Then I tried installing v2.39 which works fine. I hope I'm not missing out on any important new features.... Thanks for the great app btw, I wish there was something half as good for mac....
