Okay here's my situation:
I've just got my computer back from being repaired, no viruses, clean hard drive, the internet connection works, and I go to install City of Heroes.
The updater runs for a couple of hours and as it is almost done, I get an error saying that one of the files my be corrupt and the updater would have to verify them. I let it run overnight, and it is still stuck on fixing texEnemies4.pigg. All it does it get to 5.3 M/1.2G and retarts. Can anyone help?

Thanks. Now it's off to the search.

Odd situation. I've created a supergroup and now I'm trying to recruit my alts. However I cannot find a way to do so. Can someone help?

I'm sorry if these questions have been asked before, I just wasn't able to find a guide.
Question 1: What is a good secondary for MA. I see most people choose SR, would Invuln or WP be good?
Question 2: Is MA good for PvE?
