Hey thanks for the feedback...actually I have manually entered the parameters from one amp the the other ( from the Spider Valve IV 120 to the MK II HD 100 ) and surprisingly enough the MK II didn't sound too much different from the other amp.
Spoke to LIne 6 support and your right, there is not another work around for this.
The only way to bring the patches over is to manually enter the parameters from the Spider Valve IV to the MK II and then once loaded in to the MK II ' tweek ' them in as best you can to match them up.
