primo2.exe encountered serious error must shut down

my trusty binatone died (screen blank) so got hold of a Chinese mediatek gps on the cheap running igo

igo8 doesn't route me properly for truck use and was running primo2.4 of here on my binatone, so deleted igo8 off the Chinese gps (backed up first) and then put primo2.4 (one that I was running on binatone, minus save file) on the mediatek, so far so good, re did navpath and primo started, went through all the usual setup things like language, voice etc, all ok, detected gps and then locked onto satelites, great, so I thought, when I exited primo it shut down ok, then go message "primo2.exe encountered serious error must shut down", when I re starded primo had to set up voice etc again,(didn't have to select language again) any suggestions?

thanks in advance

I think it's a license issue, I had kind of the same. Take a look here:
