Reinstalled OS on my Mac; How do I re-pair Yojimbo on iPad to new Mac install?

[The Son of Abraham]

Hi,

I'm having a problem with Yojimbo for iPad. I reinstalled the OS on
the Mac to which Yojimbo was paired, and now I can't re-pair Yojimbo
on my iPad to the new Mac OS install. I use Yojimbo often to keep
e.g. travel documents with me abroad, so this is an annoying issue.
I've seen some other posts on the forum about similar issues: I also
just get the notice that Yojimbo can't find the old machine (although
the new install has the same name, so this is a mystery). I can't
find any scope for resetting the pairing on Yojimbo for iPad in order
to re-pair it.

How do I overcome this?

Cheers,
