I myself had this issue, magix crashed when i was downloading the content pools and other downloaded content would download again and again then show that it was installing but would never get passed a meager 16th of a progress bar. Go to the main program settings and click on the "clean up store" button in lower right this resets your paid for/ downloaded content to a scan from 0% state which will allow you to re download items if it were the first time, then press the "rescan soundpools" button below the clean up store button. P.S. this process will also clear out any unwanted clutter from your loops visual folder in the browser get you all visually reset and stuff, have fun guys i will post any other exploits i happen upon take care...
