Query: Big Disappointment!!!

I HAVE WINDOWS 7 ON MY COMPUTER. I CHECKED WITH BROTHER BEFORE I PURCHASED PED-BASIC & WAS TOLD IT WAS COMPATIBLE -NOT! THE UPDATED DOWNLOAD INSTRUCTIONS DIDN'T WORK. CHATTED ON LINE WITH BROTHER SUPPORT & WAS GIVEN DIFFERENT DOWNLOADING INSTRUCTIONS. DID NOT WORK. CALLED BROTHER SUPPORT -3 DIFFERENT TIMES- A LONG WAIT EACH TIME-GUESS WHAT! .....SENT IT BACK THIS MORNING. COST ME $11.00 TO RETURN IT! DON'T PURCHASE IF YOU HAVE A NEWER WINDOW SYSTEM ON YOUR COMPUTER.
