You did something wrong..

Are you sure you deleted you {IL-21946 Game Folder\files} and your {IL-21946 Game Folder\MODs} folders?

If all is pooched....I hope you have a clean copy of IL-2 1946 patched to 4.08m

If not:

Install from the DVD 4.07m and patch it to 4.08m then follow the instructions for installation of the Unified Installer

If you do:

Uninstall and delete the mess you have now; then Drag another copy off of your clean install and install the UI as per directions.

My best,
D
