Calender's Schedule-A-Meeting bar & interface disappear

My Calender normally will have the Buttons such as Schedule-A-Meeting, New, Tools, Filter. Then below the buttons, it will have the Day/Week/Month format tab and the calender entries. But now they are all disappeared?

I shared my calender with my secretary, she still able to check my Calender entries and all are still there.

Is there any settings that I can set to retrieve the previously look that I have in my PC?

Subject: Standard client or basic?

Have you upgraded your client? You may have been using the Basic version and have upgrade to the Standard.

Try opening the Basic client version by going into your Notes program directory and double clicking on nlnotes.exe (the program directory is c:\program files\ibm\lotus\notes by default, but may have been changed during installation).

Another possible cause is that your mail file template was upgrade from an R6 or R7 version to an R8 or R85 version.
