Okay! I can only help you if you have Windows (I know NOTHING about Macs!)
1) Find a website with a Disney font. (
Like this one!)
2) Download the font.
3) It should pop up with a box like this;
4) Click OK and it should pop up with a window with items in it.
5) On the left hand column, click "Extract All Files". Looks like this;
6) It will open a New window like this;
7) Click Next and then Finish and this window will pop up;
8) Move this window to the side and open the Fonts folder by going to
START -> MY COMPUTER -> Local Disc C -> WINDOWS -> Fonts
9) Drag the True Type font into the Fonts folder Like this;
10) A little bar will pop up and fill itself in, then it's downloaded!!
It's kinda confusing so if you have questions you can PM me. You're going to have to do it for EVERY font you find, so it can be time consuming if you have a lot of fonts.
Good luck!
