I loaded a style (_TBSW164) and the corresponding demo project in the style picker. I then made some changes to the project and accidentally saved it back to the original name. Now I have lost the original "_TBSW164 Demo (Country, Nashville TeenBeat with Piano).SGU" file. Is there any way to get back the original SGU file that goes with the WMA file? Or would I have to reinstall BIAB?
