Starlancer11, judging from the date stamps of your messages it would seem that a whole month has passed since you reached mission 10 before your computer died. I think a savegame of that mission would be worthless to you now because at that particular point in the campaign there is little chance for practicing your skills by freelancing etc., but you'll need those skills a few minutes later.
You'll probably have much more fun if you replay the campaign until you are in Chugoku again, to regain your lost skills. This can be done fairly quickly - say, four to five hours - if you use certain tricks to speed up your progress. I have posted a plan with detailed steps in a
similar discussion in the spoiler forum.
I think you'll enjoy the replaying the battles because they are much easier for you now, and if you reach Kyoto then you'll be in better shape for the things to come. If there are certain missions that you'd rather not fly again then you may have been approaching them from a wrong angle or with ships/weapons that make the missions more difficult, like trying to use heavy fighters instead of light ones. You can get tips in the spoiler forum. If you cannot find the answer in the posts that are there already, just ask.
