I bought my M5 on oct 21st of this year, just a few days ago my Mode select button stopped working when you press it in, however the encoder still works when you turn it.   I just want to know how or what i can do to send it in for repair or replacement.   I bought it from guitar center and after asking them they claim i need to send it to line 6 because it is out of their warrenty period (66 days old, and their warrenty is 90 days-1 year....)    Thanks for the help.
