Well I tried all combinations of the patch, patch 1.1 and the two versions of the program. The only combination which would start is patch 1.1 with EP0000248680 and as someone else mentioned previously, that crashes during registration.
I'm looking it up now to see if there is a way to get it working.
Just to clarify here, do I need this to be done a PS3 with official firmware? I thought I saw the remote play option say that it needs to be done through PSN. I assume an ethernet cable from the PS3 to PC will work?
Well, it looks like I found the answer myself. A simple restart before attempting to use the program gets it working and it connected fine. The only problem is that the quality was atrocious, here I was thinking it would output 720p, I should have known.
