Hi. Until I go back to uni (in a few weeks), I cannot use my xbox online due to my family home having a router which has too low MTU which cannot be changed. I have continued to play offline, earning achievements and such. I was wondering If I use my live acccount with Games For Windows Live, as i have a hankering for some DoWII, would that make me lose my achievemnts earned on my xbox? So basically do I need to sign in to live with my xbox before using the account on windows. Many thanks. As a bonus, anyone got any clever ideas to get around the MTU issue? Take it using ICS won't help.
