There's nothing I am aware of. I think the majority of folks have no issues. I have no ideas why its not working for you, and its nothing to do with the command line, it's generally very stable software as most folks here will tell you, more stable than a lot of software. All I can suggest, is if your that keen to run GameEx you try reinstalling windows and starting from scratch with the latests versions and drivers. By the way, that command in the log is kind of pseudo, to test the Game on its own look at the run last game link in the program group. GameEx creates a batch file .bat everytime it runs something and runs the .bat file (I dont think your realised that HK).
