For 5% error, according to SAS:

5% crash on loading indicates

~You just upgraded Il2. During this you missed an SFS file Somewhere. Go back and repeat.

~You just installed a mod enabler. Then , also you might have missed an SFS file (could happen with some enablers) or, your copy of IL2 is a direct to drive copy bought over the internet.That means One of your SFS files and some of your dlls are spiked by UBI. The fix for this is here: http://www.sas1946.com/main/index.php/topic,1531.0.html

~Somehow your soundsetting is something other than 44.1KHz, and this is somehow screwing everything else. I personally have never been able to reproduce this crash. But know about it anyway, Access your sound settings through the IL2Setup.exe , or IL2SET.exe in your game folder. This seems to apply only to old UI installations anyway. One of those "funny little spies"

~You did nothing and now there is a 5% crash. One of your SFS files somehow got lost or corrupted. Count them and replace them if needed. Copy all SFS files over from a backup of your game

If you can, you install it on another pc with Windows XP and copy the entire il2 folder on your pc.
