SX5.5.1 Midi Driver Fail

    Hi Guys,


    Been running my virus TI Desktop for a few weeks with no problems. I recently upgraded to Cubase 5.5 and I started getting midi driver fail message.


    I've tried all the usual restart unplug etc etc, when i try to reinstall the software it blue screens the first time, then lets me reinstall the second.


    It will then work for 1 project, if i then close and/ or reopen another it will fail again.


    Any ideas?


    help would be much appreciated...tearing my hair out over this one.



    Cheers.
