UR22 Driver crashes Adobe After Effects CS5

Just wondered if anyone else has had conflict problems with UR22 driver and Adobe AE (CS5).
I have been running this copy of AE and all the other Adobe progs in the CS5 Production premium suite,
on an i7 quadcore processor in 64 bit Win 7 Pro, for about 2 years with no problems.
Then recently, I bought a UR22 and installed it on this machine. Now when I go to set audio output mapping
to the UR22 in AE preferences, AE crashes and I cant load a new copy untill I remove the UR22 driver.
All the other Adobe progs (Premier Pro, Soundbooth etc) in the CS5 suite still run fine and allow me to
ouput map to the UR22.
Can anyone help ?
I have sent an email to support.
