sansa express switches off when trying to use voice recorder

Hi All,

Need some help please.

I have a sansa express 2GB UK version.

Firmware 01.01.12E

(flashed it quite some time ago).

Use it regularly - no problems until today.

Wanted to use the voice recorder. Something I have not used in ages.

However, when I start the recorder the player switches off.

So I power up again, try again, same problem.

Again ideas how to fix this?

There is no memory card plugged in, currently about 150MB free space,

battery well charged and audio player mode is working fine.
