Not that I want to post this twice, but having explored just about every other avenue, I've realised that this is possibly more of a Support issue than it is for the Scripting forum where
this was posted. I've submitted a support ticket much earlier today and so far haven't received a reply, and in the meantime I've been trying various things to no avail. If support could see it at some point, I'd really appreciate some feedback on what's happening to it. Both issues aren't ones I can sort out from this end.
