I picked up my PSP for the first time since April since Ive had internet problems and when I went online it said, "A patch update is required to enter Infrastracture. Please download and install this patch through the XMB."

So I went to the XMB and downloaded the latest software update which was ver 6.30. After that I went back online and it still said the same thing! What patch is this talking about and how do I download it! Please help.:)
