Confused PRS-300?

[ktdawe]

My PRS-300 keeps hanging and the buttons stop working...  device is fully charged (several hours) and worked fine when was just unplugged from charging.  After a couple of hours being switched off has stopped worked properly (buttons don't work, doesn't remember the last book I was reading... remembers the one before) etc.  Have tried re-setting it - several times.  Doesn't fix the issue.  Can't manage to get it to do a hard re-set- don't have enough fingers/hands! (and don't think buttons working properly).

Any suggestions?

thanks
