I had been using University edition SAS Studio quite success for a couple of weeks; however, now when I attempt to start SAS studio I get the error message: Unable to create temp directory. Then I am redirected to the the SAS knowledge base documentation.
At a guess, sounds more like a host start-up issue than a client connection issue.
If you were to re-download a fresh SAS Studio and start it up, do you get the same problems? If so, sounds like there's some clean-up required within your original SAS Studio host (assuming you choose to keep it).
