My site has decided it only wants to ship to my country, but I ship internationally..

I'm using ZenCart 1.3.0, I haven't upgraded it... but my ISP did a big upgrade last week and it has caused a lot of problems... mainly with shipping but I've pretty much ironed them out by removing them all and then reinstalling them all (Flat rate, delivery mod, pickup and zones until I discovered when trying to test Zones that I can't select any country other than my own on the Order Form (New Zealand).
And a comment has arrived underneath with
"Please note: We accept orders for shipping only within New Zealand."

Before this upgrade we were accepting international logins and shipping internationally.

I've spent the last 4 hours searching the forums and all I can find is posts wanting the opposite. I have my country zones reloaded, free shipping is currently disabled.

Any suggestions?
Thanking you in advance.
