Ok tell us what you have put on,

You should install like this for 4.08 mods
Stock 4.07 -> stock 4.08 -> English sound mod -> ac installer -> wrappers.dll
In that order?

But to be honest you should go HSFX 4.11

Delete Il-2,

Re-install il-2

The go like this,

4.07 -> 4.08 -> 4.09 ->4.09 skins -> HSFX 4.0 -> HSFX 4.1 HSFX 4.11

Hope helps
