Help! Messed up the menu

[iNeb]

I was messing with the menu in kde via menu editor and now my internet folder contents went and mutimedia is gone too, how do i reset it?

To return to default settings you can delete the user's hidden .kde & .kde2 directory (in the users home directory) and then restart KDE -be advised, you will loose your KDE settings for that user.

-or-

You can use the menu editor to examine those entries on another users KDE and recreate them on the problem users menu.

You're using mandrake? From your other posts I'll assume you are.
Mandrake uses debians menu system to manage its menus - hence the tool menudrake. It allows it to have a single menu system for each WM, hence reducing the overhead of work required to install a new bit of software, also installing from RPM allows you to automatically add menu entries this way.
Try deleting the .kde directory (it may be .kde2 or .kde3.1 depending on your installed version) as CMonster suggested. If that doesn't restore the other stuff, try running menudrake and see if it is there, if it is, save it.
If in fact you are not using mandrake, I apologise for waffling on like that, and the deleting the personal KDE directory should work fine.

No, i am using slackware 9.0

And i don't want to loose all my kde setting, but i might have to

lol, sorry.
I've looked at the kde directories, and found what looks like the menu in ~/.kde3.1/applnk/ It may or may not work deleting that on its own. If it works it should pull the other menu from /var/opt/kde or wherever it is stored on your system. If it doesn't work, you may need to delete the whole thing. (personal settings dir, not KDE itself )
