Logitech wireless mouse and keyboard. Wireless mouse and/or keyboard not registering. Changed

Question

Wireless mouse and/or keyboard not registering. Changed batteries in both mouse/keyboard. Frozen. Turned off computer several time. When the window comes back up it says "analog." Does that have anything to do with getting the mouse/keyboard working, this is the best I can explain. Thankslogitech keyboard and mouse will not operate even after i put in new batteries..... I have the same problem ..mouse and keyboard just quit. Replaced batteries in both still not working! This is the second wireless keyboard and mouse I have bought. The first quit after about 9 months...went back to Staples where I bought it and they gave me a credit and told me to update. So I spent more money..but this one is just over a year old and I don't have the bill. My solution to the problem is don't buy another Logitech...they are only good for a year!
