How to put music in a custom map, and my "Create a character" button is gone. Halp TT^TT

For music, look here.
And I don't know what you mean by the button is gone.
You just, log in, and then there is a "Create" button.

About the button i don't know really, probably you messed with the layout by installing a mod in to the game, could be the layout itself or just the button texture, in the last case the button should be there but invisible. If not, try reinstalling.
Or maybe you have reached a limit of character, but as far i know there are no limit.

I think you should re-Download. Maybe it didnt completely download.

I have deleted a map I downloaded from someone, and have re-installed the game. The "create" button is stil gone.

i have about 100 characters.

Believe there is a character limit of 100. You'll have to delete old characters to make new ones.

Your probably right. If you have too many, they won't let you make any more. So I suggest deleting on or two of the least used avatars.

Adding on: Maybe you could take a screenshot so you could remember them
