Tomb Raider:Chronicles Freezes

Can someone tell me why Tomb raider chronicles freezes,the game works fine until it freezes randomly.I have been burning games (self-boot,non-selfboot) since july and I never had any problems until now,is it something I did while burning or is it a bug in the game???

same for me, tv goes black just after the boot logo.
and in the vmu screen stands "Tomb raider".

Guess we have to wait for a fix patch.
