Channel 1 stopped working [Solved]

(Writing here as asked by support because I can't seem to post in closed forums)
Please may I log a support query. I can't seem to find a forum lost button so apologies for the private message.
I have just purchased the DVS 7.4 system, got it working right away with my x2 Technics Mk2's and my external mixer.
Was all wokring great for a bout 2 hours when suddenly channel stopped working right in mid mix, music went odd and then no sound (works fine in bypass mode) - after running install wizard (many times) it never seems to pick up and sound from input one and 2.... (but bypass is fine???)
I have see a few forums posts about trying reset.exe, I have tried this to no avail, just resets my config which I have been doing.
Can you please help with any suggestions?
If it helps - my physical connections are in check. Desk are into respective 1&2, 3&4 - respective 1&2, 3&4 outputs to phono inputs on mixer. Master out plugged in from mixer.
Thank you in advance
PS: As I am at work right now, config report and some screenshots of your audio settings will be uploaded when I get home.
