Has your camera always done this? Or is this a recent problem.
Also, have you changed your memory card, and that has caused your error?
Some times if you use a higher capacity memory card than the camera can use (especially with the xD card format) you will encounter very wierd errors, as the camera is trying to read or save to the card.
One thing to check is the memory card type. Olympus uses the xD card, BUT in the last couple years they have changed the format, from an xD card to an xD card type "M". The type M has a different file structure, and older cameras, and ones that can't support the "M" format might give odd errors.
I checked Olympus' website and I did NOT find any drivers for your camera, which is odd. Try uninstalling and reinstalling your software, and also check your memory card. If you have an extra around, try using it (I wouldn't recommend go buying a new one as many places do NOT let you return memory cards).
Let me know if this helps!
