MP crashes on startup (1 Viewer)

[red_zebra]

Hello Team MP,

seems that I need your help: MP crashes on startup and I have no clue what could be the problem. It worked just fine some hours ago, and I didn't change anything but installed a new game via Steam in the meantime (and I doubt this could be the cause). The problem occurs even when I try to start MP configuration. Could please anybody see the log files and provide a solution? Thanks in advance!

Looks like your Arial system font is replaced or missing (can't say exactly as errors are in German)

Is google translating correctly?

Exception: System.ArgumentException: Die Schriftart Arial unterstützt den Schnitt Regular nicht.

Exception: System.ArgumentException: The Arial font does not support style 'Regular'.

That is only the first exception. The there is:

Indeed, it was the Arial Regular font - I would never have thought about that (although I noticed the error in the log, but I didn't take it seriously). Besides, the crash occured far after the "initialize fonts"-message on the startup-splashscreen. But nevertheless, it seems that Bioshock 2 indeed broke my system font - thank you, Steam! Well, however, for those who face the same problem one day - download and install this: http://www.microsoft.com/en-us/download/details.aspx?id=16083
