[DM800SE] EPG Fails to load

Hello,

I'm having troubles with the epg on my E-Star DM800se(frontprocessor V3)
When i first boot the box and load crossepg, it Works fine...

When the "auto epg update" at 4.00u starts the box reboots and the epg is completely gone.
Then i Restart the box and manual load Crossepg it's back again
It seems that every time it crashes the epg.dat is completely gone from my hdd

Please Help...
