I've just bought a sunburst 600, but had no Workbench. I bought Workbench separately, with the CD and USB interface, connected it all up using the floor box marked XPS-AB, and tried to run Workbench. It said nothing was connected. Got the same answer with Monkey v1.06. It can't "see" the Vax. I'm puzzled - what am I doing wrong. Line 6's website won't let me raise a support ticket, it seems it doesn't recognise the guitar I have. Any ideas, guys?
