Couple of issues : BF109 Loadouts and 109E4 lacking power

You might have misclicked when trying to adjust the fuel and ended up momentarily clicking on the gun slots, then when you clicked out of it to close the drop-down menu you have accidentally set them to empty. I know because i've done it too a couple of times

In any case i'm glad you got it sorted out, now have fun flying it
