This thread was for more than a year ago, and any problem that GSX might have had with SODE jetways in the past has surely been fixed. In addition to that, the log posted clearly indicates there's a problem with that scenery jetway:
This line in the SODE log:
"No 'jetway.cfg' found. Unable to move Jetway..."
Shows a file which is required to create a problem SODE jetway was missing so, clearly, it cannot be a GSX problem, since that file is supposed to be provided with every SODE jetway, otherwise it will never work.
