Can you retrieve data from olympus VN-4100PC voice recorder which has just stopped working showing an "ERR" message on screen? Also what can I expect to pay?

I have an Olympus Digital voice recorder VN-4100PC. How can I move recorded files to a computer

The ERR indicator is only active if the DVR detects errors related to decoding of video/audio. These errors are due to discontinuities in the received or recorded file data.

You're right..This happens often when one changes the battery.Here's what to do :
The ERR message can only be corrected by holding in the DISP/MENU and STOP buttons for two seconds, which results in ALL the material on the recorder being erased. It will say (FOR) for a few minutes while it is erasing everything, then will work again.

chk err

Solution is very simple - just press DISP/MENU and STOP simultaneously for 2-3 seconds. There will start the FOR blinking on the screen of recorder (ERR will disappear) and the red "eye" on the switchboard. Wait for few minutes and your recorder is back to work :)

Warnning: This means FULL restart and you will lose ALL your recorded data! But I did not find any other solutions...

Purchased an Olympus VN-4100PV digital voice recorder a couple of months ago at Radioshack. (no software came with it)
Recently purchased new PC with Vista 64-bit. Recorder will not work. Called Olympus today, 12-3-08 and was told no driver is going to be issued to remedy this situation, thus rendering my device useless.
Thanks for nothing Olympus product support.

yes the above solution ie by pressing "STOP" button and "DISP/MENU" button at a time is solved my problem showing "ERR" in VN 2100PC olympus voice recorder

Download the digital wave player and install it. That will work for your VN-3100PC http://www.olympus.it/consumer/2590_software.cfm?category=0&productgroup=347&product=421&os=7&result=
