Forum:Change Sims3package to Package

I need a help. Does anyone know how to change Sims3Package file to Package? I wanna to install Twallan's Master Controller. But, the type of the file showed that's a Sims3Package file, not a Package because I already installed S3PE. So, I uninstalled S3PE and hoped that the file type would change. But, it wasn't. Please help me!  Dini  ( Let's talk! )  12:57, May 5, 2013 (UTC)
