"Upon some investigation i have found that if you are not within the UK you may not be able to activate the game as it may be region locked to the UK.
This information will need to be clarified with Steam themselves as the game has not been released as of yet but The Steam Forums are temporarily offline for maintenance.
I personally did some further investigation & found this here: http://www.giantbomb.com/the-elder-scrolls-v-skyrim/61-33394/skyrim-pc-might-be-regionlocked-between-eu-countries/35-514804/
It'd be good if...i dunno, we knew something about this before the orders are dispatched so that we can cancel? Come on Bethesda/Zenimax, give us something concrete.
