Downloaded and installed the concorde and the Project A380 airbus. Both show up in the panel and allow me to select them to fly. I click fly now and "all objects loaded" comes up as normal...and then just hangs there. HELP!
Something is wrong with one of them.
Loading more than one at a time is looking for trouble, you don't know which is bad.
Make sure FSX is working. Delete both and then load one at a time.
