Addon Conflict: Aerosoft Seychelles X and FS Global 2010...any help?

Hello everyone,

I am experiencing the issue discussed in this thread:

http://forum.aerosoft.com/index.php?/topic/76790-seychelles-x-mesh-issues/

According to the conversation there its caused by a conflict and not by seychelles X itself, which is why I post it here. Anyways, at FSIA the default scenery is mixed up with the addon, buildings sink into the ground and my plane is around 10 feet in the air.

Here is what I see at FSIA:

Strange: I can temporarily fix this by deleting all files in the ProgramData/Microsoft/FSX/SceneryIndexes-Folder as described in the thread, BUT if I launch FSX after some time, the issues are back. Doesnt exactly make sense.

my money is on some file on FSGlobal 2010 conflicting with SeyX, so has anyone an idea which local file of FSGX needs to be deactivated?

thanks
