if you have IL21946, or the series collection, or forgotten battles, find the file (in the il2 sturmovik folder) il2fb.exe copy it, and rename the copied item to il2.exe ( .exe being the file type) so you now have one of each.

this solves on of your problems, but having solved this one, i still couldn't get mat manager to work, but it means i have at least specified a path to the exectuable that mat manager uses to work (which is the il2.exe file. However, your game needs il2fb.exe to run, hence you need both).
