Locked Character
Thanks for posting your updates, TheLurker. Exact same thing happened to me with Beam Rifle. Another log in fixed it right up, but there were a couple minutes where I was getting riled up.
Justice Superteamer
Current Project - Water Blast Superteam starting Friday, 7/20/2012.
Come out and join us Fri/Sun 8pm ET on the "Justice Superteamers" channel.
All players welcome!
Heh, same thing happened to me today. But, logging again did fix it, as mentioned. I guess it was able to make whatever connection it requires, the second time.
Kind of annoying, and misleading, but not earth-shattering.
Please try MA arc ID 351455, "Shard Stories: Scavenger's Hunt." Originally created for the Dr. Aeon contest, it explores the wild potential of one of the City's most concept-rich but content-poor settings: the Shadow Shard.
Same thing just happened to me and a relog fixed it.
Got me pretty riled up for a min - this should be fixed ASAP.
EDIT: Meant to say that it also cleared out all of my power trays too....
Go Team Venture!

After the patch I tried to log in my Titan Weapons character and got the following message:

"The character is locked for the following reasons:
Your account does not have access to the power set Titan Weapons.
Would you like to enter the store to unlock your character?
( Yes ) ( No )"
I already bought Titan Weapons.
This needs to be fixed asap, please.
Edit: Same with Street Justice
Edit 2: nevernind, logging out and back in fixed it
