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

Thanks for your reply,

I checked my main.dll and it seems to be the right one... having looked at the files included with the freeware chinook, I think I added in two files into the modules folder, Traffic.DLL and TrafficInfo.DLL, but these were for FS2004 not FS2002. I (stupidly) probably overwrote them without creating a backup, then when FS2002 didn't load, deleted them from the modules folder incase they weren't supposed to be there. If I get the two original files from the FS2002 CDs, will they still work, or do these files change with time as you add in other bits (like custom AI traffic)?

Thanks,

Jamie

Thanks for your help guys, I have managed to get it working now. In the end I just replaced the two .dll files and this seems to have worked, now I just have to get all my ai stuff working again... this could take some time! That's a good idea though for the future Hagar, I'll do that if I have any further problems.

All my custom AFCAD files seem to have gone, do you think there is any way I can get them back or will I have to rewrite them?

Thanks again,

Jamie
