Throughout all of this hassle, I hadn't actually had an antivirus installed. I got one this morning though, set PSO to the exceptions list.. no luck. Also turned the AV off.. with no luck.
Though to make it clear again. After installing, the game loads up to the start screen fine. There is some stutter in the BGM but the game DOES load up. Once the game shuts itself down AFTER downloading the patches, it is impossible to start the game again. It doesn't even open the game window. I get the feeling that something in one of the 7 patches does not agree with my computer.
As it stands, it looks as though PSO will never run on my PC. Shame, was really looking forward to playing it again
Thanks for all the help and suggestions though guys, much appreciated.
