Virtual Memory is used when your RAM is completely used up and your PC still demands more. Your harddrive is then used to simulate RAM and handle the rest of the load. Typically your harddrive is slower than your RAM, so you get reduced performance once you start using your Virtual Memory. Try avoiding having to use virtual memory at all if you want peak performance!
Apparently you have too many programs running and taking up all of your RAM and then most of your virtual memory. It's possible that before you opened Anim8or, a lot of your virtual memory was being used already. This could mean your system is running slower than it possibly could...it's recommended you uninstall or disable any programs from starting up upon login, and make a search for spyware, adware, malware, or viruses that could be clogging your system resources (try out
Spybot Search & Destroy--Be careful with what you fix though! Also update your antivirus software or replace it with something better)
There are a few things you can do:
1. Close all programs out except Anim8or. This will free up more RAM and reduce the amount of virtual memory required.
2. Increase your virtual memory allowance (paging file size). Follow this article for directions:

Typically with stock computers/laptops you can upgrade to 2x the amount it currently has. However, make sure you verify the maximum amount and type of RAM it can handle before you go out and buy it (or let a computer shop handle it--more costly though). I recommend newegg.com for cheap memory.
Hope that helps!
