New browsers don't work and freeze the majority of the time specifically for SLR converted files. There's no problem with downloading the Original files, separately, one at a time, with FDM or a certain unsupported piece of software (not browsers).
By using FDM with its add-on to lift the link, and then inserting the link into that unsupprted piece of software, it is possible to download uncorrupted files, one at a time.
Look on the forum and you'll find a certain locked post that says more.
