Starting Parallels Desktop 3.0

Before I start, here are my computer specs:

Macbook
2.2 Ghz
2 GB 667 MHz DDR2 SDRAM
Mac OS X version 10.5.8 (Leopard)

I hope that somebody here can offer their advice. I installed Parallels Desktop 3.0 on my computer. However, when I try to start Parallels Desktop I get an error message that says: The application Parallels Desktop quit unexpectedly. It gives me three options: ignore, report, or relaunch.

I tried relaunching the program and got the same message. I also uninstalled, then re-installed the program. I get the same message.

Has anybody ever encountered this problem before?
