After installing the 2.50 firmware update using line 6 Updater, I come to a screen that says "Please wait, loading important post-update instructions." It seems stuck here, the instructions never load. I tried just pressing continue, but found I did not have the two new amps in my factory 1 or 2. What is going on? What are the important post-update instructions I need to follow? Are they why I am missing the amps? Thanks
