I can't play my own track

I made an awesome track but I can't play it outside the editor, every time I save it it says something like "the track has low performance." , and I can't see it between the track I've downloaded from other users.

Do I have to save it in a different way ?
I have a starting checkpoint and a finish checkpoint of course. I don't know what is wrong, I've been working on it the whole day, please help.

edit: If you could only tell me step by step the BASICS to create a playable track (even if it's a short straight line), I would see if I'm missing something
