ART Digital MPA with MR816

Has anyone ever used the ART Digital MPA with the MR816 via ADAT? I cant get it to sync properly. I can get either a very distorted signal with the ART sample rate selector on ADAT, or almost a clean signal but with something not right with it when its on normal 44.1. I have tried every possible way to configure the ART, i cant get a normal clean signal . I was thinking of either trying the S/PDIF out or wordclock out.

Did you ever sort this out? I just got one of these from ebay. Did you sync it to your PC via SPDIF or wordclock?
