It's the same thing with the version numbers changed, Blizzard changes the version number with every patch, last time was 4114. This is why everytime something gets patched, Cosmos breaks instantly.
Actually I got a few of the things back that I have been missing since the retail patch. Tackle box, more UI options, along with the Thottbot uploader options. Has anyone had any luck getting it to update since they turned it back on? I know it hasn't for me.
