My computer decided it no longer wants to communicate with any of my Xcal2's. I can still datalog, but can't connect Liveload or my PRP software to the Xcal2. Does anyone have the drivers for these tuners? I thought I still had them, but apparently I was wrong. Naturally SCT said they can check to see if it's a software issue, but I'd have to call in and I work when they're open.
