A few weeks ago I purchased a Mustang GTX50 amp. Love the amp, but for whatever reason it won't download a software update. I'm connected to Wifi, and follow the procedure of holding down the button while turning on the amp. Shortly after a message "Searching for updates . . . ," appears then, " Downloading updates . . . " But nothing happens. I let the amp sit for a few hours and still it reads "Downloading updates . . . " Is there something I'm doing wrong, or is there an issue with the amp? WiFi connection was confirmed. Thank you for your help.
