Hi I am here with the same problem, I think now its impossible for me to rollback to 1.71, line 6 just walked away from the Variax users, line 6 monkey obsolete now, the line 6 central doesnt appear to see anything. Disgrace line 6. I also have a Helix that wont connect to PC, service centre tells me it needs in/out board '@ £400 plus installation, more than the unit that never left studio is now worth. Its time for me to walk away from line 6.
