I am getting the following error: "The client cannot update your Dark Age of Camelot installation because a large number of key files are missing or corrupted." What could be wrong?
Be sure to download all of the critical update patches for your current operating system from [1]. You can also do this by clicking on the Start button and clicking on the "Windows Update" icon.
Also depending on the expansion make sure to check for stand alone update patches for your installation at [2]
