I know this error is probably posted throughout the forums but I am going to post it once more.
A friend of mine installed tremulous just 5 minutes ago and it was working fine, but when I asked him to go to trem.tjw.org/backport and download the windows version of the backport and overwrite the existing tremulous.exe it gave him Could not load OpenGL subsytsem.
If any reasons why please reply or refer me to the correct topic with the issue.
Thanks so much.
