Jr. I have had the same problem from time to time. come to find out I had to restart my computer, also I have a cable that runs from my computer up to my desk that had a bad connection that game me that error also,. Once i fixed the connection problem its been ok since and the other times i just had to restart my computer for some reason even though I programmed it , and was successful, still would give me an error, and would have to restart the computer and check it again.
Not sure if its the same error . but that is what problems i had in the past.
