If you have purchased the game in Steam sometimes before MP4 update, you should be able to see it in your library.
If you purchased it outside, e.g. Maniaplanet store, either contact that store support, or directly Ubisoft support.
But you might need a proof of purchase.

do you know what kind of proof? Because i bought the demo version, i dont know the exact name, but the one before the final release and i'm afraid i lost the receipt and i only know that i bought it from maniaplanet web site. Thanks for the reply.

The proof of purchase is the mail from the shop that shows that you have purchased the game.
Or a copy of the bank account bill where the shop has got the money.
