When an account is blocked, the IP it is on is automatically blocked for a day or so (unless the person setting the block unchecks that option). When the block is removed, the autoblock on the IP is not removed. So you either have to use a new IP or ask for the autoblock to be removed through Special:Contact.

I've removed all the autoblocks on that wikia.
