I'm not sure this is the right place to post this -- I'm new here -- but I need assistance restoring the usage of my Cellink Bluetooth BTST-9000A wireless headset with my desktop computer.  I had it working, but then unplugged it so I could install it and use it on my laptop (which works fine), but when I plugged it back in, now I can't get it to complete a connection and re-set up the earphones and microphone.  Here is a description of what is happening:

With the laptop (and this was true with the previous connection on the desktop), I turn it on, then double-click on the blue oval in the taskbar and open the Bluetooth settings.  In that window, there are the icons for the headset (over the head design) and the mike (the little ear hook thingy).  Then I click on File at the top left, and click Connect.  It connects and is working. 
Now, on the desktop computer, when you turn it on and open the Bluetooth Setting by double-clicking on the blue oval in the taskbar, you'll see in the BT window NO icons!!!  So I click on Open New Connection at the lower left to set them up.  That takes you to another screen where it shows that the computer does acknowledge the BT9000 (if it's not showing up in the window at first, I click Refresh and hit the "pairing" button on the headset and then the computer will find it).  Then when I need to do the connections to set up the earphones and mike, THAT's when it won't connect to do so.  That's where everything stops and I can't get any further.  This is where I need help.  I get the prompt "no connection" so I can't connect to set up the Audio Sink or the Headset.

I have tried uninstalling and reinstalling, and when I do that I get the prompts, "Failed to enumerate monitors" (I have no idea what that means) and "The RPC server is unavailable" and "connection to remote device failed."

Yes, it is in "discoverable" mode and, yes, the two lower com ports in the appropriate window for that setting are checked ("AV" and I can't remember the other right now).

Any suggestions?
