SkySim DC-9

Anyone else had an issue with the brakes being jammed on after take off for the SkySim DC-9? Normally if that happens it's usually the autobrake is still on RTO after take off, but in this case that's not the problem, the brakes just will not go off, forcing me to land with the brakes jammed on after making a flight, and then of course I can't taxi off the runway, and in reality that would probably not be a great way to make a landing either of course.I did read somewhere this issue was something to do with FSUIPC and could be sorted by reinstalling that, but I tried that with no joy. Any suggestions gratefully received as it is a good fun aircraft in FSX but I don't want to land it like that!Al
