been getting the same thing all night. even re-installed client twice. earlier this evening i was able to log in and update my addons then in the middle of updating client froze and i had to reboot pc. thats when i started getting the error message. i uninstalled client then re-installed it and kept getting error, so i did the process over again and still kept getting the error. then i logged onto website and checked the forums and seen that everyone else is having the same problem.

Agreed - I did a bunch of updates around 10-11 pm EST but when I tried to log in again around 2am, it wasn't working. It's probably just temporary, I'd guess.

So far, I like the curse client. It's not as full featured as the old JWoWupdater but I can work with it.

Windows Vista users, with new patch WoW folder is moved from Program Files to Public Folder.  The client originally installed to Program Files where old WoW folder was & kept getting error.  I uninstalled curse & reinstalled to the new WoW folder in the Public Folder & everything worked fine.

Hope this helps.
