Cubase and kemper amp

I wonder why cubase 6.5 does´nt remember the sp/dif settings?
When i do a template in cubase everything work alright the first time
but the next time i start that template, the sp/dif output/input is silent
i go from my kemper sp/dif out and to sp/dif input on my soundcard
which is a presonus FP10 i put the internal sync to sp/dif on the soundcard
and everythings works lika a charm, but as said the next time i´m starting up that template
nothing happens...dead silent?
Has anyone of you had that experience?
