Ensoniq EPS 16+ "ERROR 131 - REBOOT" when using midi SysEx

Hi all. First time poster. I have a quick question that neither the internet nor the manual has not been able to provide an answer for. I started trying to send samples via midi sys ex and the samples transfer into my eps 16+ just fine. I can play them back etc., but as soon as I try to edit any parameter, I get a message that says “ERROR 131 - REBOOT?” and the whole machine freezes. Do any of you have any idea what is happening there? Any guidance would be deeply appreciated. Take care.
