You can also check your Downloads folder to see if you still have this app already in your folder (from your original install); depends on how often you clear that folder.
The uninstaller didn't even uninstall the application. I had to manually put into trash and restarted. Now I have a persistent process named BlackBerry-Link-Helper-Agent that won't die. Looking for a way to exorcise RIM (as they still call themselves on their web page) from my MacBook.
