Solved Lotus Notes

Hi everyone,
I have the following issue with Lotus Notes:
When I first used lotus on my home PC, it worked fine. For no reason, I get the following messages now:
a. Bookmark File does not exist (I then click 'ok')
b. You cannot quit Notes because a dialog is active. Switch to notes first, close the dialog and then exit Notes. (I then click 'ok')
c. File does not exist: mailbox.ntf (I then click 'ok')
What is it???How to fix it?

Hello! First of all try these steps
1 Open the "Start" menu and click "Computer" or "My Computer" depending on your version of Windows. Navigate to the C drive.

2 Open the "Notes" folder. Double-click on the "Notes.ini" file to open it in Notepad.

3 Place a semicolon ( in front of the following two lines to temporarily disable VirusScan:

AddInsMenus=NCMenu

EXTMGR_ADDINS=NCExtMgr

4 Click the "Save" option from the "File" menu. Close Notes.ini.
