I'm new to this but I have a 300 and have installed all the latest workbench / monkey software but the box won't see the guitar - always have the red flashing light. I've made sure I'm using the power supply etc and have uninstalled / re-installed the software. The only thing I haven't done yet is a reset on the guitar - will that help, even if it still has all the original factory settings? Any help gladly received.................
