Sounds like you have an autoexec.cfg with your name in it.
Either change it in there, or remove it so your name will be saved in q3config.cfg and will remember to what you last changed it into.
Try doing /seta name yourname in the console. Either that, or you can go to your q3config.cfg and change the name in there. q3config.cfg is in the baseq3 folder and in every other mod folder you might have. If you want a new name for everything, you would have to change them all. Makes sense?
That wasn't the cause? Please don't start a new thread if you didn't solve the problem in the previous thread. You could have posted in your previous thread that ASE wasn't the cause, if that is the case.
