As I've said, are you still getting that error you posted above ? If yes, NOTHING in GSX will work, since without the airport cache, GSX cannot work on anything. I already suggested a possible solution to try, which I'll repeat it here:
- Restart Windows
- Remove this folder manually:
C:\ProgramData\Virtuali\Couatl
- Restart the same, and be sure you wait the cache to be ready and the message "airport cache loaded successfully" comes out.
