When I try to download the PS3 beta, it says I don't have enough memory. The download screen says it needs about 6 GB, and I have a little over 9 GB of free space on my hard drive. I deleted everything I didn't want to keep and added a 32 GB SD card, yet it still says that there is not enough space. The FAQ site said that 12 GB PS3's were incompatible, but mine has 74 GB total. Do I need at least 12 GB of free space on my hard drive, or is there a certain place I need to have more memory?
