Thanks for the heads up. From the console, it seems not to be related to letter case sensitivity.
The problem that people have mentioned before is the symptom, not the cause, as each one of them couldn't start the launcher for different reasons. Anyway, I will look into the matter today. Don't know what time is it in your country, but here is early morning, so, I will look at it in the evening, when I get back from work.
Thing is, the Launcher needs a rewrite, but I don't have the time to do it. And in an
early thread for the next major upgrade (a complete rewrite), people didn't seem much acceptance for a new version for OS X- only, so I decided not to do it at the time.
I was away from the forums for a while because I have a real work now as a freelancer, and I imagined that my little launcher would have been replaced. Seems this is not the case, as I still see many users and I may need to reconsider making FS2_Launcher 4. Time will tell.
Until I see what's wrong, I need you to delete the Launcher's preferences and your command line file. Refer to
this page to see how you will do that. If the problem persists, please post back here, with the console crash report.
