I can't transfer my files from recorder to pc

This problem can typically be solved by unplugging the device from your computer's USB port and plugging it in to another USB port on the same computer.

Also be sure you have Olympus Digital Wave Player installed and open with your Transfer Options set to Auto Transfer. To do this, follow the steps below:

Open Digital Wave Player > select Transfer from the menu > select Transfer Options > under Auto Transfer, check the box which reads "Transfer all audio files after detecting Recorder."
