Everytime I try to acquire a license (that I should legally have, they're for
streaming video services I've purchased) with Windows Media Player, I get
error message C00D11CD, "unknown error". "Windows Media Player encountered an
unknown error. This can occur when another program or operating system
component encounters a problem but does not communicate the nature of the
problem to Windows Media Player."

I have no idea what to do, someone please help!
