In case you don't know, you can easily have as many versions of IL2-46 as the size of your HDD will allow? Simply make a copy BEFORE you make changes! One setup for each version if you have the HDD space. Right now I have 2 500Gb HDDs and at least 1 copy of each version back to 4.05 including 3 vesions of 4.08. One for tinkering with, one without mods for on-line play and one which is never touched and obviously my back up. I have 2 4.09s one with mods and one without mods. And is as simply as making a copy! In fact I NEVER make changes to the off-line copy until I've tested the changes 1st in a copy ditto for my on line 4.08 and the un-modded 4.09b1m. Get it?
