Azbox HD - MGCAMD problem - stop

I am using to send emms Mgcamd to OSCAM upgrade the card. The version 1.35 that I downloaded directly into azboxworld.com not run. The I downloaded the 1.35a here on this forum works and sends the emms, but from time to time to stop Mgcamd "BUS ERROR". Any suggestions of what I do to solve this problem?

Azbox Premium HD+ 0.9.5309

Sorry my bad english...
