No matter how I try I can't pair my bluetooth keyboard with my windows 10, 64bit pc. The keyboard appears, I click on it and it says connecting then I get the message that it can't be found and to put the pin again but nothing appears to put the pin and the first few times I tried to pair I had a pin number but it still wouldn't pair. Now all I get is the name of the Keyboard and then it just stops and says "try again". Bluetooth is "on" and updates are all correct, bluetooth and windows 10.
