Most of us had to relink, i managed to log into FTB the second attempt after the relink message. Relinked my account and all is fine.
Most likely going to be a few glitches after the CFUK plugin upgrades, as for the vanilla banned message broonie will have to fix that on the banlist.
apologies for the inconvenience at this time but keep trying to log into FTB, it should go through and you can do the standard relink using your code from the link account page on here.
You'll be able (or should be!) to link from Direwolf too
Personally i couldn't log in to DW prior to linking. Only tried once though since it gave me a message that I wasn't linked, went on vanilla to link and fixed the problem =)
