As I was typing my original reply (which wasn't getting much help since Google didn't help as much), I checked one more site. And someone else with the problem had replies from people and someone posted something to try and it worked for 2 people (the only ones who replied after it). And just ot make sure, your running Windows 98/ME right?
Here's the link. Read the directions he posted CAREFULLY. And as he said, make sure to backup your registry just in case you delete the wrong thing and can recover the registry. Also, I'd recommend making sure you have your Win98/ME disk handy just in case.
