I've had mine about a month or so now and had absolutely zero problems, until it was time to change the batteries. I've got the mouse working again, but can't get the keyboard working - it seems to be found, and the passkey displayed but the keyboard can't enter any characters. One other concern is that if I use the Wireless Link from Control Panel the keyboard isn't recognised as such, it's listed as just a bunch of letters and numbers, not an MS B/T keyboard at all!
I've done all the usual (reinstall drivers, check batteries, power, other USB equipment, driver issues, MS knowledgebase) but still can't get the keyboard working....
Anyone got any advice besides returning it to the supplier and getting summat else?
