@dberteljr said in After BAS update - error saying fingerprint switcher key is missing.:
so i uninstalled BAS, and put the old version on. worked fine. but when i let BAS update, then it gave me the error again. it's an issue with the update...
It's not a problem with the update, it's a new algorithm. Now you can't apply a paid fingerprint without a key, even if you downloaded it and saved it to a file.
