ACTIVE Unable to reactivate North America after installing another scenery

[kerrygipe]

I recently installed Earth Simulations' Guernsey scenery. I read about the issues that this scenery may have with Orbx scenery, and as per the recommendations I had read, I deactivated North America prior to installing the new scenery using FTX Central.

Now, I can start FSX just fine with North America deactivated, but when I reactivate North America using FTX Central, and try to start FSX I get the message below, followed by a CTD. Reselecting FSX to default with FTX Central allows a normal start up with no issues. Does anyone have any suggestions on how to repair my North America installation?

Error message is as follows:

Hi there,

at what point does the CTD occur, when you first start up FSX or when you try to load a flight? If the latter have you tried a different location/time-of-day/aircraft?

Cheers, Holger
