maybe wrong com_hunkmegs setting

it's default at 56

Try 128 or 256.

Tried both didn't work, it just goes loading screen b0_beta6 and stops there.

Look in the console to find the error message it gives.

put it in baseq3 folder

or you can try: /writeconfig idiot
setup ---> reset
/map b0_beta6 (if it doesnt load, download it again from other source)
/exec idiot
look in the console for variables that will be changed upon restarting
/vid_restart
if it crashes, its one of those variables doing

make sure you have the map copied into the cpma folder as well

why would you want to copy something in there?
anyway, I met the guy on the server and he said it got magically fixed

Yea sorry as my nickname says i'm an idiot it said on restarting so what did i do!? i vid_restart lmao so eh yea i restarted the game and obivouisly it worked what ix said.

I had similar problem and i downloaded map again from http://q3a.ath.cx/
