Logitech Di-novo Mac edition Keyboard not Working

[Blow up tre1]

My logitech di-novo keyboard has stopped working.

Have put in NEW batteries-went to a store and bought brand new just in case...
Was working up until yesterday, same comp, same drivers etc.
Hasn't been smashed around or anything.
Caps lock key's light doesn't work.

Power light is STILL working and it will register the keyboard is there in the system preferences logitech customising software with "Unknown" battery life/

Wondering if anyone else has had a similar problem, or if I should just contact logitech support... (need to check warranty...)

Any help would be much appreciated as i otherwise love this keyboard!!!

Warranty

Turns out they have a five year warranty on them.
I'll just take it back and get a new one!
Then I'll have an awesome keyboard again

Awesome keyboard replaced

Took it back to where I got it (streetwise) and got it replaced.
Turns out from their testing that it had just mysteriously died.
So now I got a NEW keyboard, which is again a JOY to type on as well as a NEW 5 year warranty!
Turns out it was just a dodgy product, no fault on logitech's part.
Still highly recommend this keyboard.
