Hi Dave
Sorry to hear about these problems.
I upgraded to X2 when first released, but had some strange graphical issues, so went back X1 pretty quickly.
Loaded the X2a patch, but I didn't think it addressed the graphical weirdness, so just kept using X1.
That was many many months ago, and to be frank until a proper bug patch is released, I shall just stay with X1 - X1 is a mature and stable product for me - in the short time I did use X2, on reflection there was nothing feature wise that would really make me want to change from X1 = stable to X2 = glitchy.
With regards to soundcard, I have an RME Fireface 800 - the first one I had after MUCH hassle and some not very good customer support was declared faulty - luckily I had purchased this from Sweetwater and they ended up sorting it out for me - RME themselves were unimpressive to say the least.
I also now have a MOTU 896 Mk III - better product I think and a MUCH better company to deal with.
Hope all gets sorted
Nigel
