HELP! !!!!! I deleted something and some of my programs dont work !!!

Deleting .dmg files shouldn't be a problem, unless you weren't installing your applications properly. When you installed these apps, did you correctly drag from the mounted .dmg to the Applications folder, or did you just double click while the .dmg was mounted?

If the first, then you'll have to download the .dmgs again, only this time install the apps properly.

 

They are .dmg files that had the apps on them correct?

Just download them all again...this time, drag the application into the Applications folder on your hard drive, you can then eject the disk image and safely trash the .dmg file. If you have those apps in the dock, you will need to remove them from the docl and re-add them later with the new copy of the application in your Applications folder.

In the future, remember that a .dmg is just a disk image...you should copy the application to the Applications folder if you are going to use it regularly.

 

I think that you will have to reinstall everything, why were programs in your documents folder though?
