I've found them under "Calendar". Cool.

The same here. How can I restore tasks?

It's in the phone memory, but I might have moved it back and forth some time ago. If you wish I can do some testing - write what should I do.
The ES manager has root rights.

I didn't get any errors. Do you use exception swallowing?
Anyway, I managed to make it work again. I put the MyPhoneExplorer into startup queue with ES Task Manager. Perhaps there were some access rights missing?

I was happy MyPhoneExplorer user, until I rooted my phone. Now task reminders don't activate at all.
(I really must had rooted it, because of slow responsiveness caused by too much bloatware on it.)
Is there any way to make it work again?
My phone is HTC One V.
