Hi,
Ever had this error “The exception unknown software exception (0xc0000417) occured in the application at 0x00a13c18″.
Solving it is easy, just erase the .AUC files in the folder:
C:Documents and Settings*Current user*Local SettingsApplication Data
Or for Windows 7 / Windows server 2008 users:
C:Users*Current user*AppDataLocal
