Yep, SupportUK@gamesas.com - though be warned, all they'll say is to try the rudimentary steps you no doubt already have. They are very polite but sadly they don't seem to be able to give any concrete info on anything.
Thanks for that - I'll give it a go. I've also made sure I've worded my e-mail appropriately so they won't be able to tell me to do any of these rudimentary steps (I've included a list of things i've done, including "turning my PC off then back on again", because tech supports seem to be a massive fan of this one). Fingers crossed I'll be able to actually play this game come next week. Heck, if I had the money, I'd buy a darn 360 and an HDTV and play it on that, in spite of my disdain for consoles. I'm turning desperate here!
