Just to update: I have cleaned, formatted, etc my PS3, other games seem to be running fine, there seems to be no major issues that I can tell. Yet, since the last maintenance which did not have a version update, my PS3 has frozen in a 2-5 minute window frame of logging in, multiple times. Sometimes I am able to log in for 15 mins before the freeze. I was never having this issue to rampantly previously, but I am not suggesting it was something changed during that maintenance - it is just a timeframe/flagpost.

I have read through the many other forum comments on this issue, as well as looked at other websites for helpful info. I think basically I am just going to have to cancel my sub until I can afford a PC or PS4 to play, sadly.
