The name is already in use. Try another name.

I've just tried launching ADOM 1.2.0p8 (Windows) on Windows XP and when I try to create a character with my desired name it gives out the following message:

The name 'Enivid' is already in use. Try another name.

The ADOM folder is empty (safe for the game executable), so where does it look for a save file with that name?

EDIT: Forgot to mention that when I am trying to restore a game, there are no save files available.

It's looking from the %USERPROFILE%\AppData\Local folder.

My best guess is that there's a save game from an older version still lying about. You can't restore the game because it's incompatible, but you can't create a new character because the save file is still there.

Thanks! Found it at C:\Documents and Settings\%Username%\Local Settings\Application Data\ADOM\adom_dat.

It might be worth mentioning that due to the fact ADOM stores savegames with 8.3 filenames, you will also get this error if your new character shares the first 8 letters of its name with an already-existing one.
