compatibility with motu m2?

[Eatz-altf4]

ive been trying to get SAR setup with reaper and the motu m2 recent and have had no luck, reaper jsut keeps telling me that asio couldnt be initialised which ive gotten as an error before but now all the fixes ive tried for that ion the past arent working. reinstalling reaper, SAR, and Motu drivers seemed to do nothing. reaper works if i take SAR out and just use the motu asio so im confused as to why SAR is having problems.

I have to Motu M4 and could SAR with 256, 128 or 64 Buffer Size but not with 512.
