hmm.. ok, I've forwarded this on the the tech support guys. They'll have a much better understanding of that kind of stuff than me. (especially if it's anything to do with the Windows operating system and not Mac.)
The only thing I can think is that I used to get that type of thing happening on my old computer. (a Mac G3 ... one of those small purple colored things) Mainly because of an outdated operating system and not enough processing power and ram.
I'm assuming that your computer isn't 5 - 10 years old though :)
Pretty much anything these days with at least a couple of gigs of ram should be able to handle the flash player.
Either way though, gather your system info for when the tech support guys get this message cause the first thing they'll probably want to know is what kind of computer you have etc.
