Windows Media Player 11 for Vista 32 bit Home Premium Edition

My Windows Media Player 11 freezes up when I try to watch a video from a link

and /or site. I just got this laptop last week, and the Media Player worked

fine for this for a few days, and now everytime I try to watch a streaming

video it doesn't download it and it freezes up right away. I can't even lay

it down or close it. All I can see is that circle going around and around

next to my mouse arrow. Any suggestions on how to fix this? I would

uninstall this media player and re download it, but I don't see any option

for this =/
