Had to refresh Windows, now all my BAT are gone

I had about $45 (48BAT), but due to my laptop running into problems, I could do nothing else to sort the problem other than “refresh”, but once everything was back on all my browsers/passwords/bookmarks, the “key” to my Brave awards had gone. When I re downloaded Brave it was though I never had an account, cannot log in, and when it says enter your email, I never get any verifications.

Can anybody help please?
