I hit some button on the user face of the amp and I lost all of my presets. So I went to the Manual and it said to hold down the exit button, and turn the amp on and it will factory restore. So I did that, and it did nothing. All I have basically is a white screen where the presets were. I installed Fender Fuse, and that hasn't been going well either. My computer keeps telling me that it is trying to Sync with my amp. How do I get the amp to factory restore? There has to be a way. Any help would be greatly appreciated. Thanks.
