Hi!

I had the same problem in the same situation.
Try to install other drivers from the factory CD. It didn`t work for me,but try it maybe it will work for You. I bought a Midiman Midisport 2x2 midi interface and I don`t use the serial port any more, because this interface has an USB connection. It`s perfect for me. You can find some info at www.midiman.com .
