Installation Problem after informing admin name

Hello,

I'm using Xampp in a XP machine. Phpmyadmin works great. MySQL and Apache are running perfectly.

After I unzip the package, I point my browser to
http://localhost/pp and I can do all the 4 initial steps.

Then I get the following message in step 4:
"You have installed ProjectPier successfully. Go to http://localhost/pp and start managing your projects (ProjectPier will ask you to create administrator user and provide some details about your company first)."

There I inform the name I choose to the admin, e-mail and password. When I press submit it takes a long time doing something and most of the time Apache goes down.

Any thoughts on that?

Thanks in advance,
