Q: Cannot remove files from MacBook desktop.

Long story short, my MacBook Pro running OS X Mavericks will not allow me to move or remove files from my desktop, stating that I do not have proper permission. I am the lone administrator on this computer, as no one else uses it. I have tried almost everything, yet nothing has worked. I cannot move, rename, or delete any files that are on my desktop, nor can I add any more files to my desktop. This is extremely frustrating due to the fact that I practically run my life using this computer. Any help would be extremely appreciated. Thank you
