If you are having problems that require the replacement of your System Folder, you can indeed replace it. However, please start the replacement procedure with the complete backup of the Studio volume. Accidents do happen, oversights do occur, and the simple backup procedure is the professional approach to the possibility of an unexpected occurrence that results in disaster.
Many professions have metaphors for taking the steps to insuring the avoidance of the unthinkable; choose whatever metaphor you like but, please take it to heart. Only the inexperienced or the cocky will fail to effect the simple backup procedure.
