Ok I tried to dl other customs with different filesharing site..... zippyshare, dropbox... it does basically the same thing. It would ask to choose which app to use to open the file for download. When I download, the files are either in binary files with p.psarc or m.psarc extensions. I was able to download Cherub Rock from the ignition page and played it just fine.... I also downloaded another paid song Supermassive Blackhole by Muse, though I haven't played that yet. Am I just not able to download custom downloads from Customforge?? I'm feeling a little dejected :( ... Any help would be awesome. Update: I just tried to play the new song I bought and downloaded - the Supermassive Black Hole by Muse - and it plays fine but now I can't find the Cherub Rock song from the list in Learn A Song. Cherub Rock is in the list of DLC in Steam, though. I looked for that hidden dlc folder in my Finder and now the only song that's there is Supermassive Black Hole one. Cherub Rock is gone... Update again: Nevermind. I found Cherub Rock and put it back in the hidden dlc folder in my Finder. Now it's back in Learn A Song in RS. Now back to my original problem of downloading CDLCs.... Anyone?
