I performed all of the following:
1. factory reset
2. reformat external Card
3. fix and reformat Internal memory space
It still doesn't work.
Can someone please try the following for me on a H7600: Load preset #876 (Flanged Space 1), then save the preset from the factory bank to the user bank (on any slot). Try loading the preset from the user bank. I cannot do this on my H7600, and get the error message referenced above. Given the steps that I took to reset/reformat the machine, others should have the same problem, otherwise I have a hardware defect.
