Hello again :)
Simply copy both the .cat and .mum file into C:\Windows\Temp\CheckSUR\servicing\packages (create folders if needs be) and re-run the System Update Readiness Tool. SURT will copy them back.

P.S. You seem to be having a lot of issues recently. Are these all on your own system, or are some for friends/clients? If it's the former, you must have had some pretty bad luck recently!
