How do I make it work without Making it Immovable?

No, I'm not doing pre-loaded Music, I am doing Music that the Player uploads In-game so they can listen to there own music.

When I was making my game, I gave a Coin a Physics behavior so it would behave in a cool way. But The Problem is that It keeps falling through the ground. The Ground is A Tile Map so it can make it easier for me to make Levels. (Obviously, the TileMap is solid because if it wasn't, the Player would just fall through like the Coin). The only difference between the Coin and Player is that The Player uses The Platformer Behavior and the Coin uses Physics.

HELP!!!

(If you need more Info, just ask. I REALLY, REALLY, REALLY Need as much help as I can get to solve this.

I am trying to add A Custom Music feature in to my game so The player can enjoy while being Stress free. Please help me!

Here are some Questions I have that I get from upgrading from Free version to Personal Version.

1. The sounds on the free version only let me upload sounds from 96 kbps to 192 kbps and that is hard when your trying to upload a 712 kbps sound file. Will that be Fixed in the Personal Version?

2. The Layers section only let me create up to 4 layers. Will that be fixed in the Personal Version?

3. On the export part, it only shows a few games, but on the website, it shows platforms that Didn't show on the Program like the Wii U. Plus, it is hard for people like me who want to upload there games to Steam Greenlight. Will there be a variety of platforms on the Personal Version?

I might have some more questions but I will mention them in the comments.
