I downloaded the windows program to upgrade my code50 to latest  version...everytime i try to run the program it shows loading then disappears...nowhere on the screen...how do i use this to check for upgrades..im hoping that theres is a patch to fix the editing the preset names problem.  seems  when holding down the store button to get the left scroll if you hold it too long it goes to save...if not long enough nothing..sometimes you get it just right and get the left scroll screen.sometimes the amp locks up and it has to be turned off then on again to rebboot..and you have to redo..
