[XB-49]

You're problems are a side effect of installing mods, I believe they are not fixable. Try pressing the windows key when you're cursor is frozen. That should bring you back to your computer's main menu. Then get back into you're game and everything should be fine. I'm afraid you'll have to live with the high number of crashes. Try not to click anything after you've clicked the IL2 Sturmovik icon.

Edit: Ever since I've started using HSFX I not had a single crash. My game also loads significantly faster than it did with UI as well.
