Error Querying Device -1
I am running into a snag on one of my programs I am trying to run. I am getting through about 3 or 4 trials and then get the error that reads: "Error Querying Device -1". I've never seen this before and was wondering if anyone knew what it meant. It does not give any other specifics. I am thinking it could be an issue with the button box connection or possibly the parallel port that I have connected to use for this program? However, I use the button box and parallel port connections for 3 other programs I am running and they all run fine. The only difference on this program is that I am showing videos instead of static images. Could that be the issue?
Any help would be appreciated.
