This all started when I had to reset my settings on PS3 to fix problems with it starting up.
After doing that I put on Fallout NV, loaded and game and I get the message, 'This is another user's savefile'
Shocked slightly I put on COD BOPS and it wouldn't load...
Tried it on a new profile that I hadn't played BOPS on yet and it worked...
What is wrong with my PS3?
This happened during the current PSN downtime if that helps....

What problems were you having starting it?

It wouldn't start at all...

How did you reset your setting then? What settings did you change?

Are you using a different account to load those saves? For example a save-file played on user ali8283 won't work on another.

@dragonborn
I entered safe mode by holding the power button for a while and selected the option reset settings to factory default

@ali
No, I'm trying to load it from the profile I created the save on.

Your account info doesn't match that for those saves. A similar thing happens on the 360, and you won't be able to use the content before verifying yourself on xbox live. Since PSN is down, you're probably SOL (unless you are just using the wrong account)

So I have to wait till PSN is back up...oh well...
