(If you don't know what the portable app is -

I have run the runme.bat file, and have put the gamemode files in the add-on section, but when I load up the game, they aren't in the menu.
If I select the "custom" gamemode, and go to the menu where you can select which add-ons to use, they aren't there either.
On an unrelated note, I have to enter my key each time I boot up the game this way.
Any way to fix this?
