I have downloaded the Arcadia 5 main collection and extracted everything to a new folder.  When I run the Coinops executable, I only seem to have access to 4 of the horizontal icon categories.  I can get to Favorites, All, Settings, and the controller icon.  Pressing left and right will not let me access any of the seperate categories built into Arcadia 5.  Only 112 games are showing by default as well, and I know there are many more than that.  Where should I be looking to find out why everything in this build isn't showing?
