Hey

I'm a complete stranger to illustrator, i just got the tryout version, lol. However, the program won't let me use the font's i want to use, i get this error when i try to save the file with text in it:

"an unknown error has occurred"

What the heck? Anyone know why I get this error, and how i could prevent it, and be able to use all my fonts in illustrator and on prints?

Thanks in advance,
Jake
