I had the same problem. Doing some research, I found windows had an update around the same time the game stopped working. I got rid of 8 and put 7 back on, cause I hate 8 without a touchscreen. I'll let y'all know if it works.

First check u have allowed both dbo.exe and dbo launcher.exe to firewall exception list and try running again if that fails then
Perfect uniinstaller - delete remaining game folder - reboot - reinstall n it should work if that fails, perhaps when u downloaded it, it was corrupt so re download it.[/B]

hey if u could tell me how to put dbo n launcher as an exception that would really help

This is a known issue with windows 8 and DBO: http://dbocom.com/forum/showthread.php?t=37497

If that guide doesn't work, you have to wait until Wasabii fixes the problem.
