Endpoint protection says it is out of date click on fix

Version 11.0.4000

Open symantec endpoint protection and it says antivirus and atispyware protection definitions are out of date.

It is a client of ours.   The date for them is aroub 4 months old.

It says click on fix and I do that and nothing happens.

I have ran a repair and know it has been rebooted multiple times since the date of the last definition.

So ?
