hello sorry for the intrusion but my laptop shutdown unexpectedly whilst my bitcoin core was still in synchronisation and i was 2years 13 weeks gone.Problem is anytime i try running the app it shows me "error loading block database,do you want to rebuild the block database".
How do i proceed as i have already received coins which i have in two separate addresses and can not afford to lose this coins.
please users i need your advice.
