My level doesn't go up

If a game has been previously free it doesn’t grant any CV. When you select a game to give away, you may see it has a * or ** next to the title. If it has one asterisk, it gives reduced value. If it has two, it gives none. Check the FAQ if you haven’t already

If you mouse over the gifts sent on your profile - they are considered to be "No Value" games.

These do not contribute to your CV (Contribution Level) because of this and so won't level you up.

If you want to make sure a game gives CV in future - make sure that when you search for the game within the New Giveaway page that the game doesn't have two stars next to it - that indicates its a no value game.

** = No Value

• = Reduced Value (Some CV)
  No star = Full Value (All the CV)

If only i'd get 10 cents for every thread like this, i'd be rich.

I really suggest reading the rules and faqs.

but I had 1 level before.

Sorry...

I just gaveaway more than 5 games and my level still 0 ..
what happen?

As others have already mentioned, giving away free games does not affect your level. I suggest you read these:
