Depending on the type of error, the problem may or may not be solvable.

You can try reinstalling that particular app by double clicking the app icon in YouWave's left panel. YouWave will reinstall the program without removing its app data. However, if the error is from an internal issue in the app data, you may still facing the problem. In other words, if the error is from the corruption of the app data itself, you cannot recover without cleaning up the app data.
