Ok, it won't let me get past the mission "Onslaught". I did beat the campaign, but that was with a different computer. But get this: After I died 5 times and it came up with the dialog box asking me if I wanted to skip the mission, I clicked advance to the next mission. Guess what it did? It sent me right back to be briefed on the exact same mission again. In addition to that, when I did actually complete the objectives (The Cypher got out with about 83% health, the Minos got out without a scratch, the two cruisers were disabled out of range) and return to base when it tells me to, it then says that I failed the mission. Even though I know I didn't and the debriefing said that I didn't fail it. Why is it doing this?
