Thanks for using our answers forums. When you say the virtual remote won't work, what seems to be happening? Are you not able to find a correct remote, it is correct but doesn't change channels, etc? The articles listed below should help you further with getting the virtual remote programmed and working. The bottom article is not directly for WoW, but you will still want to take a look at it and make sure this isn't what is happening in your case.
- Advanced IR Emitter or Onscreen Remote Control Troubleshooting
- IR Blaster/Remote Control Troubleshooting for older Slingbox models
- My cable/satellite set-top box is not responding to remote commands
Hope this helps!
