Saw the new build and installed, sailed through no problem, can report it's fixed, thanks very much Tim.

I did a binary search on the 300 scenery addons I've got to find the Iran :) , will see what I can do, for future would be able to put something in the exception handler for the log? If not possible then no worries.

Thanks for your wonderful program Tim, really appreciated.

Am getting the same error with Iran add on freeware scenery, is there a way of easily tracking down which file(s) are causing the problem please?
