Parallels not working Properly

Hi all

I just bought Macbook 5.1 Mac OS/X and updated software to 10.5.6 yesterday

I installed parallels verison 2.2.1970.0 and installed windows XP on VM
At first it was it wasnot working, then it started but was hanging up and i had to force quit VM, It work okay a few times but sometiimes it the round ball spins and hangs up.

How can i fix this? Should i get an upgrade for my parallels? Should i uninstall window Xp and then unistall parallels and start with a new verision?

How much memory should be allocated for RAM 512 RAM OR 1 GB?

Thank in advance for any help

Try using boot camp to set up a windows partition, then run parallels and link it to your partition. That's how I've got mine set up and I've never had a problem.
