You could always download and install Lightroom again, but usually that doesn't fix the problem.
If you could explain the problem in detail, we might be able to advice.
How do you mean corrupt? It could mean you have to reset the preferences?
Give more info so we can help such as; error messages, what is the strange behavior, version of Lr and the OS, what have you done to troubleshoot?
Hi pjotrett ,
Which version of Lightroom do you currently have?
Please explain the issue you are facing in detail.
Also provide some of your computer specification.(Like Ram,Operating system)
I mean: Is it just to throw the old one into the bin and start the new and open the last saved catalog?
First try optimizing Lightroom catalog .See How to improve and speed up Photoshop Lightroom performance
If you want to create a new catalog in Lightroom. Select File>>New catalog.
I am overwhelmed of three fast answers. I will first try to replace the programm and if that doesn't solve the problems I wonder if my own presets also will be deleted? If so it's not so good of obvious reasons. Is there a way to save them?

Your presets will not be deleted. I doubt that re-installing the program will help, and you are wasting your time doing this. A better use of your time is to describe the problem you are having.
OK dj_paige. The cloon/healing brush doesn't work, same with the toning filter.
Same with the brush (K). The white dot has disappeard (in all tools) so you can't do any changes.
Geoff the kiwi, Thank's but it did not work. The changes I do with the tools can be seen in the previews but not in the major window. And as said, the white "tool-dot" isn't there. It's gone.
Peter (It's late here in Sweden so I will go to bed now. Thanks and good night.
If you press the H key does the white pin return??
The changes I do with the tools can be seen in the previews but not in the major window.
When you say "previews", do you mean the navigator window at the top left in Develop?
Does this also happen with global adjustments?
The cause for this could be a defective monitor profile.
Try setting the monitor profile to sRGB as described here: How do I change my monitor profile to check whether it’s corrupted?
However, if you have a DCI-P3 display, you should probably use the DCI-P3 profile instead of sRGB.
This is really only troubleshooting, and if it fixes the problem, calibrate your monitor with a hardware calibrator, which is especially important since you seem to have a wide gamut monitor.
Since I don't use a Mac myself, and am no expert on color management, I'll try to get D Fosse to look at this.
As for the missing pins, Geoff is right - pressing the H key toggles the visibility of the pin on/off.
You can control pin visibility behavior on the toolbar at the bottom of the screen. If you can't see it, press T.
On a properly working computer no program gets corrupted or works any weirder than it did the day it was installed.
Your problem is more than likely a computer hardware problem. Faulty, failing, hard drive or faulty RAM. Could also be a virus but I doubt that.
Yes, the white dot did return after striking H. But the changes is only visible in the navigator window.
It just happens with the tools, not global adjustments. I will test other proposals later. Guests are coming.
Thanks so far!

In that case, it's not so likely to be the monitor profile.
Try resetting the preferences - hold down Option + Shift while launching Lightroom, and choose Reset Preferences in the following window. See also http://www.lightroomforums.net/showthread.php?25197-Resetting-the-lightroom-preferences-fi le-updated
