Unfortunately I'm getting a CTD with the update, citing video drivers:
Log Name: Application
Source: Application Error
Date: 26/11/2011 12:19:43
Event ID: 1000
Task Category: (100)
Level: Error

Description:
Faulting application fsx.exe, version 10.0.61637.0, time stamp 0x46fadb14, faulting module nvd3dum.dll, version 8.17.12.5896, time stamp 0x4c37903a, exception code 0xc0000005, fault offset 0x003514c3, process id 0xacc, application start time 0x01ccac330e2f530e.
I know that the error, "exception code 0xc0000005" can mean all sorts of issues but simply uninstalling the Wilga stops the issue.
