i recently bought crysis 2 and love every second of it. but my hard drive recently failed and now ( by what i believe) the multiplayer code can only be used once. so do i have to purchase crysis 2 again to access multiplayer????? id hate to buy it again.

No its registered to whatever 'account' you use to play online hence the Email address and password prompt's pre-game. Just remember to enter the correct details of the account you used to play on before the HDD failure. The DRM shouldnt be an issue neither. Daz
