Hello ElLobo, and welcome to Seven Forums. :)
I'm sorry to hear that you may have had trouble with this.
As a test, use the commands below at step 5 instead to unregister the wmpband.dll file to see if that stops the error you posted. This will undo the tutorial. If it doesn't help, then this was not responsible, and something else is causing it that we'll need to track down.
net stop WMPNetworkSvc
regsvr32 /u "%ProgramFiles%\Windows Media Player\wmpband.dll"
net start WMPNetworkSvc
