Our ps3 has recenty stopped recognizing any games or movies in the system. It won't even allow me to do an update on the system. When I called sony they advised me to download the update from their website and transfer to a flash drive, then to my ps3. I found the download, but my computer will not open the file because it is a pup file. I am clueless as how to proceed... I have googled it but haven't found anything that helped. Can anyone help me to open this file and get it transfered to my ps3 properly? thanks!!
