Unable to initialize font menu in Adobe CS5

I bought Adobe Creative Suite CS5 Design Standard then installed it on my PC with OS X 10.7.1. I started using it along with Illustrator and Photoshop and everything works fine. But the problem started the next time I started the computer. The program could not initialize the font menu. I am stuck with 90% and have 302 fonts on the computer. How can I fix this? Please help me.
