Segment error???

[jgss]

Hi,

I am running YDL 6.1 and SDLMAME 0132u4 on PS3. Everything was all right until yesterday. If I want to play with Mortal Kombat or MK2 then the system says "Segment error" and stops. I downloaded the game ROMs again, but stayed the same. Can anybody help? I don't wanna reinstall the whole system. Thanks for the answers.

Regards,
jgss
