Hi guys, I'm in need of some urgent help.

I have a logitech bluetooth mouse and keyboard (wireless) and they have both stopped working. I received an error earlier about a connection refused or an expired subscription and it hasn't worked since. I'm sorry that's vague; perhaps someone knows what I am talking about. I know that the batteries are not dead. The mouse worked on the windows welcome screen as it booted but then it stopped working. I tried reconnecting everything and the most I am getting is the blue light on the keyboard and mouse to flash intermittently but it will not work. My computer ... a dell ... doesn't have a port in the back to plug in my backup mouse and keyboard so I don't really know what to do. Please help? Thank you greatly. <3

Please ask me questions and I'll try to answer them if you need more info.
