US/UK import information

[iricund]

I have a couple of potential issues with the new add-on. From what I've read here and on the Ubi forums there is a potential conflict between using a UK native addon with a US copy of the stock game and vice-versa.

I bought myself a copy of SHIV whilst working in New York last year but have subsequently returned to the UK. Am I right in thinking that if I were to order a UK copy of the addon it would not be compatible with my US version of the stock game?

Quite why (and what for that matter) such a restriction would be put in place I do not know. But if I am indeed correct is there any means by which I can get hold of a US version of the addon?

Whilst I'm not particularly interested in the U-boat aspects of the add-on, in the interest of supporting the genre and in order to ensure my copy of SHIV remains future-proof on a modding front I really could do with a copy. Any ideas would be greatly appreciated.
