OK, I give up, I'll come quietly!!
Until this week I was happily running FSX:SE using PMDG, Aerosoft and iFly aircraft. I also have REX Worldwide airports, REX weather, PRO ATC X, and GSX. All these bits of software happily playing together like well behaved children.
My trouble started when I purchased GSX Level 2 and installed it as per the instructions - unusually for a very old techie, I do read manuals.
When I fired it up again it all looked OK until I tried the Jetways and it said SODE unavailable. Every thing else seems to work fine, including the passenger stuff, although I am amused at the single magic bus that deboards and boards 425 people for a PMDG 747 400.
I looked at the forum and did all the things it recommended: removed and reinstalled, downloaded SODE anew (even though GSX L2 has it already), cleared out caches etc, etc.
I finally removed every trace of GSX and SODE from my system, including all the nooks and crannys they hide in. Detached all the other addons from FSX:SE, reinstalled GSX L2. I then retreated to FSX stock aircraft. The same - no SODE. Once again everything else works so I am now stuck. I have no idea what to do so some suggestions would be helpful.
