Getting flash to see all my fonts

a few months ago, someone posted something about why flash cant read all fonts on your cpu. i made a fla doc. i use myriad pro(an adobe font) in a project. my cpu crashed an i had to reinstall everything on my cpu, windows included. now when i open up my fla doc it gives me the error cant find find use default etc. in parenthesis myriad pro is in the text field. when i open illustrator myriad pro is there. anyways, a few months ago someone came up with the solution. you have to select your fonts and paste them into a folder either a common folder or a folder inside of the flash program file. i did this last time but cant remember where that folder is. also, myraid pro isnt a font thats inside my fonts folder. i wonder if someone could please help.
