The message i think you are refering to is the one about your virtural memory beign to low, and it is not fixing the problem. Right?
The easy way to fix that is to bump up the Virtural memory! (swapfile)
You do this by getting into your control panal and then going to system. Click on the Advanced tab and then click on Performance. Then change away

. I think that the default is set to 192, but not sure on that. Just make sure that you have that much disk space before you crank it way up.
This shouldnt reduce performance. It will only u se the swapfile if it has to, and yes it is alot slower then your ram. So When it does dip into the virtural memory you will notice a change, but increasing the size will gerneraly not decrease performance.
