I've tried both downloads for Zurich (FS9 and FSX), and they both works fine. Try the usual suggestions:
- Empty your browser cache, restart the browser and try again
- If this doesn't work, clear all the cookies coming from mediafire.com, restart the browser and try again
- If this doesn't work try with a different browser.
- If this doesn't work, try to restart your modem/router and try again
