[P/O W. 'Moggy' Cattermole]

load up the matt manager icon, choose a set / make changes (customise the settings as they suit you) then close down the matt manager. If you select quit, what should happen is it spends a few minutes copying all the files ready to be used over to IL2. Then you can launch IL2 normally. I don't think that selecting 'launch' from the options in matt manager worked for me, but wuitting the manager so's it copied the files and then launching il2 did.

make sure you have this:

ClearCache=0

in your conf. ini at the bottom of the column whihc starts with HighGore=1
