When you view the calendar screen it will display dates and
months that you can return to and restore that point.

Those dates are listed on the calendar in Bold numbers.
If you click to return to a previous month do you see any
bold number dates on the calendar. If you do you can select
one of those bold number to restore your system to that point.

If none of the calendar numbers are in bold letter than you will
not be able to return to a previous point. This will force you to
look for another alternative.

I am leaving the office now, perhap later tonight I can revisit
your issue and give it some thoughts on what you can do next.

it was only suggestion...
