Unable to load Version 3.2

Hi guys, I have downloaded the 3.2-Version of Catch Evolution PRO and tried manually to install it. System answer with: "Destination folder already exist ......." "Theme install failed" am I doing something wrong? (I'm a "beginner"(-: !) PS. If i open Appereance->Themes.. I read following statement: "Automatic update is unavailable for this theme." Thank a lot in advance Ernesto
