New to il2, patch problems

[Chips86]

Hi guys!!

Im new to the il2 franchise, ive just been turned by the release of the BoP demo on 360, and picked up a cheap copy of pacific fighters for the PC. I tried to update to the latest patch, but now when i go to load the game it comes up with an error message? Now i may be doing something wrong, as i am mainly a console gamer [love my hardcore flight sims though xD], so was just wondering if anybody may be able to help me with my problem?

Also i would be very open if anybody were to point me in the direction of any good mods/add ons, or anything that would increase my flying expierience.

Thanks alot in advance guys!!!
