How can I fix the runtime error I'm having on jumpstart 3rd grade on my windows xp?

Recommendation:
* Right-click on My Computer, then left-click on Properties.
* Left-click the Advanced tab at the top.
* Click the Settings button under the Performance heading.
* Click the Advanced tab at the top.
* Click the Change button to change the virtual memory.
* Write down the numbers that are currently set.
* Change the initial size to 512.
* Click the Set button.
* If you are asked to reboot, say Yes.
* If you're not asked to reboot, click OK on each window to get all the way back to your desktop, and then reboot your machine.
* When the computer restarts, try the game.
If the game fails to run and gives you the same error, please follow the instructions above and set the initial size to 256. Reboot the machine and try the program again.
As a last resort set the virtual memory to a large number such as 4000 or more and then try the program after rebooting. If this works you can drop the virtual memory by small increments until the error reappears then re-set it to the last good number.
