Can't run tremulous because I changed my settings

[TheOriginal]

Yeah, so a while ago I changed my graphics settings on tremulous to a value higher in resolution than my monitor could handle and now tremulous won't start up.

How can I fix this?

Start -> Run
enter this in the box: "C:\Program Files\Tremulous\tremulous.exe" +set r_mode 2
strike enter
