Custom made Aerial Imagery causing sim to CTD

My custom made aerial imagery for Unalakleet Alaska is now causing the sim to CTD. If i remove it from the community folder it works - and the airport file still works, but WHY would a CGL file that worked fine before now be causing the CTD??
I bring up the file into dev mode and the aerial CGL is greyed out and wont even let me load it
PLEASE HELP
