I can't create a new folder anymore

First off, I am the administrator and have my settings on full control. I am running Windows 7 Pro x64.

Ok so I don't know what disabled me from creating new folders, but there has to be a way to change it back. Whenever I right click, instead of there being the "folder" option under the "new" tab, it just shows "shortcut" in place of where the folder would be. I also opened up the "Documents" folder and tried creating a new folder by clicking on the "New Folder" tab inside the "Documents" folder. Neither of those options worked. I don't know if something got disabled or deleted, but I can't create new folders at all. I can still download and install whatever I want. It's just that I can't create a new folder at all.

Hopefully you guys will know =) thanks.

Thanks Shawn that did the trick, it works when I click on the "New Folder" tab inside a folder and when I right click the "Folder" option under "New" is there and works as well. =)

I have been dealing with this issue for over a moth. I did everything i could do to fix it. When I was just about to call it quits I came across your suggestion. I was afraid to try it because I thought it might be a virus. to my surprise it worked!!!! Thank you sooooo much for the advice!!!!

Sorry, I am not as tech savvy as others here.....do I have to click each file extension separately in the blue box to restore the default association, or is there a way to do a collective restore....can't make any folders, so I would imagine it applies to all. Please help. Thanks!
