You memory just overflowed - try not to pump it so full of junk
Seriously is it a memory issue, just means you've over run the buffer that is there to keep things all good. Try looking over your code, unless this is something that DarkEdit or DarkBasic has popped up when you've tried to compile. Cause then it means you're gonna have to reboot.
Theres a memory release bug in DB 1.x prevents it from releasing the temp source from the memory if i remember, but i dunno Dext explained it to me once when i was half asleep hehee
