tuberosity

When I go to the packer/unpacker tab to update an appID, I click on the tab to choose DLC. The navigation window is forcing me to search for file type Custom Rocksmith/Rocksmith2014 DLC (*.dat;*) Of course the files I'm looking for don't have that extension, but it won't let me change it. Help?

So I downloaded this file... unzipped it and have the guitar icon for the custom toolkit. I click on the guitar icon and it appear briefly in the toolbar, then just disappears without anything actually opening. Man, I hope I'm not missing something simple... Thanks for any help.

How does one open the toolkit on a Mac? I downloaded it, however there are exe files, but no app file. I've tried using mono but get all sorts of errors... is there someone who can walk me through this?
