Please update BRAW Studio to the latest version, as there is no 500 frames trial anymore since version 2.7.0 because decoding is now FREE ! If you converted some .braw files for proxies or into another codec (or exported a Premiere Pro project containing .braw video) before entering the license, you'll need to reconvert them again with the latest version of BRAW Studio because in them (BRAW Studio is not running anymore to make the proxies, it's inside the file)
