Getting menacing message from XP operating system when I attempt to install

At the final step of installation, I get a message from the XP operating system warning of dire consequences if I proceed with the installation. Apparently the current release hasn't been adequately tested by them. I tried an earlier release and got the same message. I installed it anyway, but haven't activated it yet. I noticed that the System Restore function on my computer isn't working properly. Could this be a cause? FYI: I read the troubleshooting page and could not find this problem in there.

It's expected, and doesn't cause problems, just click continue. All that means is the drivers haven't been put through microsoft's certification - probably due to a lack of $$$.

Thanks DrAzzy.
