One more note! When I clicked on the DimPro browser it AUTOMATICALLY updated the list all by itself. I recently purchased some DimPro librarys from DSF and they ALL automatically updated.
The reason I say this is I became concerned that something had gone wrong with the installation of the new content and DimPro was about to crash. It took almost a full minute for the process to end and there on the list was my new sounds! I don't know if I have something in settings checked or what but the new content has been refreshing the list on it's own.
If your version exhibits this behavior, just let it run and it will refresh on it's own.
