X1 Hangs on Opening

Hey,

I'm running X1b 64bit on Windows 7 64bit and I've just started using a Presonus FaderPort that I got a couple of years ago that, for some reason or another, wouldn't run on my old XP computer.  I'm using the most up to date drivers from the Presonus site.

Anyway, every time I boot up, Sonar hangs when I try and open a project.  I can get around this by killing Sonar, reopening it and removing the FaderPort from the Control Surfaces.  It will hang/freeze on open even if the FaderPort isn't actually connect so I'm guessing it's something funny with the .dll?  Once I get the project open I can open other projects without any problems at all but it's the first initial opening that causes the trouble.

This work around it fine, I guess, but a bit frustrating to have to unload and reload the FaderPort at the start of every session.  I was wondering if anyone else is having this problem or if there have been any fixes that I've maybe missed?  I can live with it as it is but something that worked flawlessly would obviously be preferable 


I've tried it with Sonar 8.5 64bit and don't seem to be getting the same problem so it seems to be an X1 problem.


Thanks in advance!
