Oh sorry i thoght that the name of the topic would be enought ;-)
Hah, sorry I can't read.
To modify your settings without starting tremulous, you can poke around in E:\Tremulous\base\autogen.cfg (if you downloaded a more recent client from
http://trem.tjw.org/backport then it'd be somewhere else, which is why I asked).
All your saved settings are in there. If you want to ever reset your Tremulous install, just move it out of the Tremulous folder or rename it.
You might also want to create an autoexec.cfg in the same folder if you want persistent settings, because Tremulous executes this file on launch but doesn't overwrite it like it does with autogen.
