I used to be fairly good at this, and I had loads of home-made scenery, ai traffic and so on, but a while ago I installed a few new downloads at once (big mistake), one of them was a GMAX chinook for fs2004 with some 'modules' (?) to install, I think I did that but once I tried to load up fs2002, it came up with the MS warning window saying there was an error with 'main.dll'. I tried everything I could think of, removed the new aircraft and module, and even reinstalled FS2002, but it still won't work.
Any ideas? I am thinking of putting it all on a new machine, but it would take months to reinstall and transfer everything I did before, not a nice thought. I would really appreciate any advice at all.
Thanks,
Jamie
