I have an N2 and will give it a go if you can supply a link to a sample

Here's a sample file if you have time to try it out. Thanks again! https://gofile.io/?c=IP6F3j (expires 2019-06-05)

I'm afraid that link has already expired :-(.

Ah sorry about that. Never used that file hoster before. Hopefully this one works better (ie: at all).
