Problem pre-ordering Heavensward in Hong Kong, Originally From UK!

[xingmao]

OK, I use a PC bought in the UK, FFXIV:ARR was bought in the UK, my account is on a European server, my details on Mog Station are UK. I have since moved to Hong Kong but use the same play set-up and my account details are the same as UK is still my official address.

I have tried to pre-order Heavensward from SE but I am told I am 'outside their service area'. I have contacted them twice to find out how to get around this situation but my e-mails have gone unanswered.

So here is my question - hopefully someone can help!

1) Is there a SE website that covers game availability in Hong Kong that I can pre-order it from? If so, can somebody provide the website address as my searches seem to come up with nothing.

2) If it is not possible to buy the EU version of Heavensward, or there is no SE that covers Hong Kong, can anyone recommend a website I CAN buy it from that covers Hong Kong? IF I end up having to get both FFXIV:ARR/Heavensward in the NA format to download instead, will this be compatible with my UK-born PC & can I still use my current account to play through (using my current characters etc) or will I have to restart all over again with a new account?

Sorry if the questions are a little dumb, but I am not techno-minded!

Thank you for your answers in advance
