I recently downloaded Lemmings for my PS3, and played through most of the levels in Fun (after playing through the 'Starter Pack').

However, the next time I went to play the game, all the levels I'd unlocked were now locked again. I can see which I've played, as my time appears with the high scores. It is a little frustrating to have to replay those levels so I can get further.

Perhaps I'll continue from Tricky and hope it doesn't happen again...

Did this only happen once, or does it continuously happen?

That's odd, not heard of that problem before in the US/Japan releases. Is this still occuring? Did you complete them under a different gamertag or anything like that?

I think I see what's going on here...

If I don't load a profile in the game before playing, it doesn't remember what I unlock. I (not entirely stupidly I think) assumed it would be tied to my PS3 login and wouldn't need to load a game. It does on Xbox Live etc. I know they're not the same, but you get used to it!

Is that correct, or am I still missing something?

Thanks for your time.

Yep, you need to load your profiles every time you start playing...
