BBC IPlayer problems - Having update troubles.?

Hi, I hope someone can help me. I'm having problems with the BBC IPlayer that I've never come across before. I've downloaded the Player and the Download Manager, but I can't download any programmes. When I try to download something, it tells me that I need an upgrade for my Windows Media Player, and offers to download it for me. I click on "yes" to accept the upgrade, then it immediately tells me that there's been an error. It just stops there and doesn't tell me what the error is. I've tried uninstalling and re-installing the IPlayer software, and I've even done a full Windows reset to try and get around this problem, but nothing seems to fix it. I've had this problem for over a week. I thought I was pretty tech savvy, but this has got me banjaxed. I hope someone out there can help me resolve this issue and get my IPlayer back up and running again. Thank you in advance for your kind assistance.
