Riight, so 2 days agoish i wanted to play some NV so i went to steam logged in and clicked play, everything seemed fine untill about waiting 3 minutes of the game to load when i clicked "Continue"
Normally it takes 30seconds to 1 minute, I tried again and left it for half an hour, Still nothing, I then restarted my computer and nothing happend, Last night i left it on ALL night But still, No. Has anyone a solution to this?

Try starting a new game and then load a previous save. This has worked for some people.
