Failing to initialise - Help??

This just happened out of the blue (as per usual!).
CFS2 will not initialise Free Flight or Quick Combat. I get the following in both, regardless of the aircraft or scenery I select.

I have done a "re-install" as suggested (both "typical" and "Complete") but this has made no difference.
I have the QC Editor installed and I haven't noticed anything unusual, other than I can't get it to initialise in QC.
Any suggestions.
Thanks
