Serial key?

[Lord_Azrael]

I bought my copy of Off Road Drive from Amazon and it installed and ran fine, no problem. However I want to play multiplayer but it's asking me for a serial key now but there was not one provided with the game. The game also shows in My Computer DVD drive as Review Version.

I sent it back to Amazon at their request and I received another copy today exactly the same!

Have Amazon taken a bad batch of review copies in that don't have multiplayer keys or have the games company just forgot to put stickers in the boxes or something? Anyone else with this problem?
