Eric, I can't help with your main problem, but I wanted to point out that your processor supports an older version of ARC. It is available here: https://www.anthemarc.com/downloads/index.php
I can't say that it will be better or worse than REW, but it is made to work with your AVM 50. Two very different approaches! However, at least current ARC works only with Anthem's own microphone. It will not work with a UMIC-1, for example.
Have fun!
