I had a problem where I was accidentally banned by DAL.net back when I first started going into the channel ... my IP got caught up in a slew of ones they were blocking for spam, so you might want to try logging in from another IP (like a mobile phone network - I was able to get in on my cell phone but not on my wifi) and if you can, send in a help ticket. It took them about 24-48 hours to get back to me and lift the ban.
