Every time I start up the launcher and it tries to patch it the connection seems to halt every few seconds, resulting in a repeating spike of activity followed by nothing. A couple of minutes later, it fails with the following:

"Unable to download patch files. [11003][10009][10019]"

It seems like generic server connection issues, but I'm the only one of my friends who's getting it at the moment. Is there anything I can do besides wait it out?
