Calendar blanks out and can't adjust entries

Love this phone! Ddesktop manager asked me if I wanted a software update which I did. Since then, I can't see ANYTHING on the Weekly calendar view (all blank) and I can't switch to Agenda/Day/Month for the Weekly view. All appointments DO show on the Agenda/Daily view but not on Weekly.
Also, once I've made an appointment on my BB, I can't go in at a later date and make any adjustments, I have to delete that entry and recreat another one .... very frustrating.
I have the new software (per the Sprint store) but has anyone seen this issue or been able to correct it?
