Hi, I've been a Guitar Tricks subscriber for a couple years but I have never ventured into the forums. I went to Fender's website to get help with this, but they have shut their forums down. I installed the Fender Tone app to two different up-to-date Windows 10 machines and tried plugging my Mustang LT25 amp into each of them with the requisite micro USB cable. On both machines, the app fails to recognize the amp and suggests upgrading the firmware on the amp. But of course, the only way to upgrade the firmware on the LT25 is through the Tone app. Which I can't do because it won't recognize it. You see the problem here. I have no idea where to begin solving this and thought I would inquire if anyone here has experienced this problem and would be willing to share a solution. Or if you have suggestions on where to find help I would appreciate it as well! Thank you!
