Hoping someone may know. So far I have attempted adjusting resolution, checked windows firewall, renamed psobb.pat to psobb.exe, and changed psobb.exe to psobb_old.exe ( I found this in another post) the program is being run as Administrator. It worked great just last night. The only thing I had done today was installed Mumble for voice chat, with the pso overlay in the pso_root. I have attempted to run the program after taking mumble out and still nothing, so I put it back. As I would like to have it.
