I've just upgraded from Windows XP to 7 and now find that I can no longer set up my 568.2MM with the computer. I'm using the same notebook PC and null serial cable (Meridian)/USB adaptor as before. The error message says check cable. I've just reinstalled the legacy configuration program. Switching the 568 off and on with the cables connected used to cure the problem, but no longer.

Any assistance would be appreciated.
