Yeah I'm having the same problem. I've been trying for two days to get the update but I keep getting kicked out. The same error msg. I think it's 8071072 or something like that. I have been noticing for the last month or so while in GT5 i will get an error msg in the top corner saying I've been disconnected from PSN/server. This is while playing ASpec not lobby. Any help? I'm on a wireless router but I'm going to see if plugging into the router via ethernet cable will help, it's just a good few metres away lol.
