Can I switch from Wordpress MU to a regular Wordpress site?

Okay, I decided it might be too tough for me to work with Wordpress MU at this point, so I want to switch to the regular non-MU Wordpress. I started a new site and transferred my database from the old site. Since the old site was MU, am I causing problems by trying to re-use the database? Should I just start fresh? Thx!!!!!
