Today I purchased a Minimoog Voyager Performer edition at a store in my city which is an authorized dealer for Moog products. My instrument has a serial Number 3783. My problem is that when I turn it on it says V3.5 in the panel, but then it prompts me to reload OS and reload Bank D which never does cause it waits for Sysex data. Then, when I try to search for Banks it only displays Bank PM. (I hold cursor and scroll but it only shows one bank). Isn't it supposed to be upgraded since it's V3.5 and its serial number is greater tha 2755?

Thanks and Kind Regards
