Ah, I see, sorry I missed the thread. I'll generate new key files, and keep a portable copy of 2.46 just in case. Thanks!
Hi Dominik, the same Key File works properly in v. 2.46, so I don't think it has been corrupted, or else it wouldn't work in that version either (isn't that correct?) Thanks
Key File not a valid Base-64 string on version 2.47
