@Fox Thanks for explanation. Fingerprints for FPS are only collected on bablosoft domains (incl. subdomains)? And I assume the remaining 50% from Custom Servers free users are also shared with paid FPS users ("With free version only 50% of your site users are added to your database, for premium users that number is 100%."), right?
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.
