I bought this model in 2011 and used it for a couple of months on a windows machine. It has been in storage since 2012 until 2017. I now have a Mac book pro and I re-installed line 6 software but I cannot get the program to run. Every time I install the software for line 6 it asks me to restart the computer, I say yes and restart but when the computer restarts I do not see the program, and when I open up applications to run the line 6 software I am then prompted to reinstall the program and restart my computer. It’s a cycle of the same instruction. Any ideas on what I am doing wrong?
