Hi everyone biggest forum I know. I've bought this old style wireless keyboard for my computer off a seller on vinted and I've bought an adapter for my computer for it but it still doesn't seem to be working there are new batteries in the keyboard and mouse but I belive the problem is there's supposed to be a cd to download the software onto the computer but it wasn't included. So I'm just wondering if anyone else has this keyboard and has the disc I could buy off them please otherwise I don't think I'll be able to use it I know its a long shot but worth a try. Many thanks in advance.
