I can watch sky player no problem from firefox & IE browser for live & on demand programs but for anything downloaded where I have to open the Sky Player program I just get an IE script error box showing:

'CliAppNavBarManager' is undefined
continue running scripts on this page?

then the start page is all corrupted & I cannot sign in or do anything??
Internet Explorer 8 & Silverlight is fully updated & I have re-installed Sky Player to no avail - when I first installed this program it loaded up no problem??

any ideas? I can locate the downloaded files but because of the DRM I cannot play them through any other player
