Sudden Problem Launching all WoW instances.

Hey, I 3-box, have for awhile, but all of a sudden IS will only launch the first 2 instances. I have been playing WoW normally, but havn't boxed in about a week or 2. I also havn't added anything new in that time. I've tried all three methods of launching that I know, and setting up new Character sets, but it always just starts two instances and that's it.

I also set up a 2box set, and only one of those instances launched. And when trying to launch a 4 char set, nothing happens.

I'm now not getting any instances at all to load, and instead am getting an error message that goes along the lines of

The CAS system was unable to initialize: Error downloading versions data from patch service: DONLOAD_COUNLDNT_CONNECT.URL:

Googling the error points to numerous threads discussing the issue, but I didn't look at them all and the few I looked through didn't have a fix, so I don't know what the resolution is.

Are you using multiple installs? Are you virtualizing more files than what the default setup uses?

Single install, and I don't know what you mean by your second question.

Also, I'm no longer getting the error message, I think that was something to do with battlenet.

Original problem still stands though.
