Unable to register Helix Rack unit


Recommended Posts



  I purchased a used Helix Rack from Guitar Center and I am unable to register the product. I have successfully registered Line 6 products in the past, but when I enter the serial number of my Helix the website errors out. Also, the site wants me to register the product before placing a support ticket which pretty much kills any support for this issue.

   A great suggestion, but it didn't work. The registration page still returns the error below.


There was an error processing your submission.

ESN could not be verified. Please confirm the supplied USN. ( Error: 523)
