What are you upgrading from or to? The 9500 is notoriously bad with the MR especially if you are using Emu v x.x? It works (just about) with v1.24 or upwards. I never got it to initialise the cam, after upgrading it, whilst I had a multicas on. I had to put 1.29 back on then mess about to get it to work, then went back to Emu.
