I have QQ messenger (Just a messenger I use with my friends) on my Macbook Pro. It had some kind of problem so I deleted it from my applications and dock into the trash. I emptied the trash because I thought that If I deleted it I could just re-install Qq messenger and the problem would be gone. I downloaded it and when I went to open it, this popped up: http://i950.photobucket.com/albums/ad343/iKawaiiChan/ScreenShot2011-09-10at81456PM.png I'm not sure what to do since I'm not good with this tech stuff. I'm not really sure where to put this question either so I just put it here. Please help.
