Uploading a game (problems)

It tells me that my filename is not valid. I tried uploading it several times and changed its name several times, yet it doesn't dwant to upload. The site I tried to upload it to is named Kongregate (it has recently united with Unity) and it DOES allow unity games, yet does not allow mine. Why is that?

I am sorry, it does work. I simply should have uploaded the web player files, not the game files XD
