Sorry for the double post, but it's been a couple weeks, so I think it's a long enough gap.
I figured out that the problem was with my EA and MM discs. I borrowed my friends discs, and it still did the same thing.
Got a new problem though. I installed everything back again (ZT2, ES and AA) but when I installed AA, it came up with the uninstallation process, instead of the installation process, which means I can't install AA, or I unistall everything. No screenies yet, but it's self-explanatory.
Thanks (:
EDIT: Where can I find the customer service number? See if I can get a new copy of the games.
