Files should appear in the depots folder with the IDs you used. • Copy&Paste or move those files to the game's original installation folder, overwriting everything; or do some fancy renaming tricks to keep both versions. [small]To find your installation directory, right-click YL in your library -> Properties -> Local Files -> Browse[/small] • Play normally. Maybe keep a copy of each installation in-case you need to do this again.
