Although 1818vsl works great now I am stuck withy 44100. I am moving 
completely to Motu in future and drop the presonus path. I am half way 
in the process of moving over actually. I tried whatever I could but 
44100 it is with 181vsl.
Interesting comment you made. Idid however tr4y all the factory resets. 
No go. stays 44100.
