1st time all went well, but I had wrong Install floppy. Got wrong sounds in some presets. For example, synth sounds where it would be kick drum, etc

Did a reinstall of presets, everything seemed to work. Turn off my e5000. When I later started it there was no sound in my presets

I have tried to reinstall my presets, several times, but the result is the same. When I restart my e5000 the presets are loaded, without sounds!?
Presets and sounds are available on the ROM card, and i can load it from the ROM card.
Does anyone have any suggestions about what has happened?
cheers
