Why is Savedata Loading in Gta Liberty City Stories?

I brought a new GTA liberty city stories in India for PSP (PlayStation Portable) i put a save data and tried to load it but it is saying there is no data. So what to do,help me with these please!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!…

Suggestion:

Maybe ur memory card is full brother… or you should try saving the game 2 times at different slots… if still dont work, try downloading the game again or maybe ur psp has a problem and let a technician fix or see it…
hope it helps…
