Game is in the middle of updating. This should be resolved once it's finished.
I have the exact same problem! No idea how to fix it =S!
Would love to have an answer to this!
And i just posted a thread with the same question x)
ok ive worked it out go to the coh directory and delete these two files CityOfHeroes.exe and Coh.checksum may not actually have to delete them both but I did and it worked, once deleted open CohUpdater.eu.exe it will open the coh launcher connect and download the missing files once done the game should work as normal.
The game was updating, and the servers were offline. Waiting 30 mins and trying to log in again would almost certainly fixed it with no need to mess with executables.

EU, Union mostly.
Anyone else having this problem or have any idea how to fix it?
After logging into my coh account and choosing the serve I wish to play on, I get this message "Wrong game version, run patcher and reconnect,server 18.20090422.2T, Client Bad client checksum - reverify files. I have reverified the files and it as found no problems.
