I have a casio fx-9750GII calculator, and I've upgraded it's firmware to fx-9860 based on a youtube video:

I don't know what's the issue here, if is any wrong configuration or something, so I need help solving this matter, thanks in advance.
PD : I'm from Cuba, sorry if my English is a bit weird .
