Not receiving updates to subscribed threads

My subscriptions to three forums and ten threads, within the TomTom group, have not sent me any 'Daily update' for the last few days. Manual checking of 'General Discussions', Maps', 'Navcore 9' and the individual threads show that there has been new posts to them, but no 'Daily updates' messages sent to me.
What have I done? What mortal sin have I committed?
I've checked all my subscriptions (for the forums/threads) immediately before this post and they ARE set to 'Daily Updates'.

Set your subscriptions for "Instant" updates. Also check your email address.

Have set 'Instant' updates and await. But cannot find how to check my email address (did look for it before posting - been a 'current' member since May 2010, received updates and NOT changed my email address).

'Instant' updates now being received - on other, previously subscribed-to, threads.
So email address OK?

A-OK!!! FFR, to check email GO: Settings, My Account, Edit Email & Password.

Did you receive the updates before?

Yes, but today I see that subscribed-to thread updates from another forum have stopped coming through! I've now set subscriptions on that forum to 'Instant' and will see what happens.
The only change at this end has been installation of a 'Security update' for my Firefox browser, but the 'Daily Updates' stopped arriving a couple of days before the update.

Thanks, it's OK, I hadn't looked far enough down the LHS (but did receive the 'Instant' updates.

Glad you got it sorted.

"Yes, but today I see that subscribed-to thread updates from another forum have stopped coming through! I've now set subscriptions on that forum to 'Instant' and will see what happens.
Those subscriptions are now coming through but those from a third forum have now ceased.

Last night I deleted all my subscriptions to 'obsolete' threads (where no postings since January 2010) and set all subscriptions to 'Instant' for the three forums in question and all seems fine today.

Thanks to tendriver for the help.
