I installed mymenu from repositories and today I decided to uninstall it.
After uninstalling it, a lot of icons in main menu disappeared and only some default have been left. Normally, I have more than 50 extra icons which are no longer visible.

I have also tried to put a shortcut of Applications manager to desktop but when I click on it, it doesn't do anything

Below is a screenshot of the menu icons left.

Does anybody know what I can do instead of format etc?

thanks
