Reply to your original ticket to reopen it. Because of the number of tickets that were already resolved by the time they were reached, they had to close all of the tickets so that they could more quickly assist the people who still need help. When asking for help over IRC, first try asking MtGox_Adam, if he's around, then MagicalTux if you don't get a reply in a few minutes. Also, don't ask your question more than once in the channel itself.
I didn't ask in the channel itself. I msg adam first and waited a couple hours. So I msged magicaltux once, nothing, so I msged him a few days later. Now I'm banned from the irc channel. I wasn't rude or anything, I msg him very politely.
