So you use a mac right? Is that OS9/X? It makes a big difference! You might not have permissions to delete it. In other words you are not the admin of your comp. You should be able to just drag & drop to trash. Highlight the folder & program & Apple & i keys, go to ownership, change it to you & make it read & write. If it's locked, unlock it. Else, start up in os 9 or your startup disk & then delete it. For os9 if that's what you're using, there's an uninstaller.
