ESET scheduled updates not running ?

Hi guys,
I'm using ESET Smart Security 4.2.22 and since last four-five days my ESET 'Scheduler/Planner is not running update tasks.' I've limited internet bandwidth w/ night unlimited (2-8 am). So I've set my ESET to update automatically at 7.30am. Earlier it was working fine but now it just doesn't run the update tasks. And if I right click on the Update task (in the scheduler) and run it manually, it works fine !
> It's paid version.
> I've tried uninstalling & reinstalling.
> I've even tried re-formatting my partition.
> I'm using Windows 7 w/ latest updates and Comodo Firewall 4.1.15

Can anybody please help me ?
You are only my last hope

Thanks in advance.

 

maybe recreate it, in case it is stuck
