You would think after so many updates and add-ons that Turbine would have figured out how to do this. But no. Connecting takes forever. When you finally do connect you're stuck at examining game data. After you do manage to download the patches several hours later, they turn out to be corrupted, giving you the message of "Unable to decrypt and deserialize the data downloaded from the server". Search the web for a solution. It suggests deleted various files from your computer. You then start over again from the beginning.
Pardon me for not being cheerful, but whoever was in charge of this release needs to be demoted back down to the mailroom.
