Ok, this is really weird.

I just used PSGroove Now Supports Retail PKGs on Minimus AVR to update PES 2011.I updated fine,but then game does not start.

I deleted all data related to PES 2011 off my console(even by using FTP).

Then I backed up the game again.

Guess what, now when I launch it, it does not ask for update.

However, the game version at the start screen still shows as v1.00.

So is it updated or NOT?
