Hi!

I bought the game yesterday and was very disappointed to find that it's crashing on start up. I tried verifying the files and reinstalling the game with no effect.

Here is the content of the log i found:

Version: 1.5.3 S

System.BadImageFormatException: Could not load file or assembly 'System.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The module was expected to contain an assembly manifest.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

End of the log.

Please help!
