Disk Image can't be open Because it is not recognized?

[DomoGoesNOM]

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.

That message usually means that the image file that you have downloaded cannot be opened, often because the image download is corrupted.
Download the file again.

I've tried downoading it again but the same thing pops up.

I downloaded it from the link on this page, and it worked fine:

What version of OS X are you running? Have you done all the "voodoo" repairs, like running a "Repair Permissions" procedure?

Well
I'm not really sure what to do I'm a first time Mac user so..
And I don't know anything about the repair procedure.
I'm using OS X Lion

Open your Applications folder, then Utilities. Open Disk Utility, select your hard drive, and click Repair Disk Permissions.
