Computer- Dell dual core 3GHz, 8GB RAM. OS is Win 7, latest versions of Universal Control and Studio One available from website.
System has been running fine and all features and controls worked well.
Problems: Main volume slider worked fine until I upgraded to Universal Control v1.7.2. Now main slider does nothing. Also PAN controls don't work any more.
Main volume can be controlled using Universal Control on PC. Pan controls don't work from either the 16.4.2 or Universal Control. I have uninstalled and reinstalled everything including a clean install of Win 7. Tech support wants $300 to repair the 16.4.2. They say it's a hardware problem.
Questions: How would upgrading the Universal Control software cause the Main fader and Pan controls to fail? Everything worked fine before the upgrade.
