Webuser Forums: Windows Media Player and Real One Player Script Error

Hi
I know I posted something about WMP before and I didn't get the problem sorted even though I uninstalled WMP11 or rolled back. I still get the message 'an error has occurred in the script on this page. I have to say I'm not very impressed with WMP10 after the roll back, I have to watch when I get a message to update otherwise it goes back to WMP11!! I have tried to remove the program and it will only roll back, I've also tried to remove it using CCleaner. I thought I would try and watch a tutorial video a friend sent and this time went to use Real One Player and the same script message comes up this time it says Internet Explorer Script Error - an error has occurred in the script on this page
Line: 1643
Char: 1
Code: 0

I wonder if anyone could help please?
Many thanks
