Trouble with Ck2 to EU4 converter.

hey I'm having some issues with the Ck2 to EU4 converter, I successfully converted a file from ck2 to eu4 and it shows up under mods in the launcher, I activated it and went into the game menu where it shows up as an active mod under content, but at this point I hit a problem, I cant find any way to open up the file in single player mode and actually play the game, does any one know what I'm doing wrong and how I can fix it?
