Well i just finshed fixing my other problem "Unable to load Subsystem" but nvm about that,
so after i open Open Arena, it turns into a black screen where alt tab or control panal doesnt work.
i have a suky
http://NVIDIA GeForce4 Ti 4200 with AGP8X running on Window XP...i couldnt find anything in the FAQ so thank you for the help.
Edit: i got the sound to work and stuff after i turned off my firewall but its all small and stuff... and when i closed it and reopened Open Arena, it went back to the same problem as before, the screen was all black but i can hear the sound of my keys...
Edit2: After i got it to work by using alt enter, it crashed and went back to "Unable to load Subsystem" error again...
