I'm happy to see this trick works for most of you !
geeman37, as the Line6 Team said, try this :
"As a potential workaround, some users have noticed that setting the Windows sample rate to 48000 Hz resolves the issue. Go to Control Panel, click on "Sound", click on your Line 6 device, click the "Properties" tab, then click on the "Advanced" tab. In the "Default Format" section, there's a drop down menu which gives you a list of sampling frequencies"
