I am having the same problem. The new release of SA seems to have been released with the S-Record file type instead of the hex file type. I also have an XTI2000 that is cutting off when the signal light is on. I have to shut the amp off and back on or change presets to get rid of the problem. The same channel has an issue with the volume knob. When it is turned all the way down, I still have sound coming out of the speakers. Not very much but some, about the same as if my other amps are set on two clicks from the off position. I have emailed firstname.lastname@example.org but have not received a response. If anyone has any knowledge about the S-Record problem or the cutting off problem please let me know.
Could you please e-mail me this information and software, I am having the same problems. Thank you. I have PM'd you my e-mail address.
