Here is some literature:
 * How to get Unblocked
 * How You Can Work Through an Admin Dispute

I don't know what happened. I can't find out. So I won't argue on that. Since it's months ago, you can hope the admin cooled down a bit. Ask him politely on his message wall here (note: he's had a rename, he's MCab719 now). However, if he doesn't want to unblock you, you've got to live with it.
