Web site gremlins (again)!

I have a rewards trip booked to Boston in March and have been trying to add my advance passenger details, as in my address in the States.
The only way I can input the data is by typing it in Word, copy and paste in the relevant boxes, time consuming but hey ho! However when entering the zip code all I get is " please enter a recognised zip code". Am I missing a trick or is the computer trying to outsmart me?
Also thinking of burning some miles on a chauffeur transfer to the hotel, just wondering what you all think of the idea?

I think a feature of the new site is that we are back to the old days and you can only enter APIS at OLCI.

Ah that's why I can't do it then. I can enter many details but it doesn't accept them. VS have most of it under my profile in FC. Is the system "clever" enough to pick up on that.

But why doesn't the system male clear that it can only be entered at OLCI?

I expect you should be able to enter APIS at any time, it's just that no one at VS knows what is going on or how to fix it.
