I got a professional license a while ago, soon after 2.0 came out, and was getting the above error. I came to these forums and there wasn't a fix at the time, so forgot about it and went on with my life. Fast forward a year or so...
Anyways, I reinstalled the system using the launcher and still get the same error. Is there a file i'm missing somewhere, or what should I do to fix this? The majority of the files in need of updating are from 2012, so i'm waaaay out of date now.
