Okay, is it a permissions issue I wonder? The exact wording of the message would be most helpful.
As for reactivations are not unlimited but you don't have to worry about it. If you get locked out just email me with your activation code and the email address you used (if you did use on) when first activating it and I'll reset everything.
All permissions are set. (I hate a computer telling me what I can or can't do). UAC is off and program specific permissions are set to full control. All folders are set to allow.
The exact wording is....
There was a problem whilst processing this flight plan!
FPP error!
I am now installing FSXSE onto networked PC temporarily to see if that makes a difference with my set up. Not hopeful but nothing better to do at the moment.(other than fly .....sheesh). But if that doesn't work then I am left with the only other possibility that I have a dodgy windows installation, so next step will be a fresh install of that. Welllll it's only my time and it's been at least 2yrs since the last format and reinstall, probably overdue.
