Well, I changed foremodel and added enemy model, enemy model didn't work, and now old rocket and plasma aren't working either. I'm not seeing my field of view neither.
Shouldn't this be a matter of deleting your q3config.cfg and maybe recreating the autoexec.cfg (since it might be a file permission issue)? BTW, if you're playing a mod, you might need to manually copy your autoexec.cfg to the mod directory.
The second line in your cfg is not executed (misses the seta command). Better to use seta instead of just set in my experience.
Deleting both the q3config.cfg and the autoexec.cfg like misantropia said is a good idea if you're willing to make the autoexec.cfg again... When Q3 is launched it will create a default q3config which you can change (preferably in the autoexec.cfg)
