just wanted to report problem solved by use ADE. The bgl was hiding in
E:\Microsoft Flight Simulator X\Scenery\0601\scenery
Still something is not right on your system. That would be the default LSZH, and it's not necessary to remove it, since the AFCAD that comes with FSDT Zurich is designed to work together with it. Meaning, there will be no conflicts if you have *only* that file.
On top of that, default AFCADs don't contain just one airport so, by removing that one, you also removed other airports in the area.
The only possible explanation is that, even if that file is named and located as the default one, you modified with an editor and, for some reason (depending your changes and the program used to edit it) it NOW creates a conflict, perhaps because exclusion areas were changed or lost or something similar. In that case, the best solution would be looking for the original file on the FSX DVD and restore it from there.
