Hey everyone, recently my 2009 13 inch MacBook Pro has been acting up lately. It has this weird problem where I can't open any applications, like if I try to open up FireFox it says "There is already one copy of FireFox running, cannot open" or if I try to open up iTunes it give me an error that says "The iTunes application could not be opened. An unknown error occurred (13014)" Skype says "Can't create lock file. Can't create lock file and /users/blahblah/library..." but after I restart the computer, the applications open up fine but it's a little laggy for a few minutes. Any ideas why this is happening?

MacBook Pro (13-inch Mid 2009), Mac OS X (10.6.8)
