Sorry, but I can't reproduce this. The FS9 link downloads the FS9 version and the FSX link the FSX version, tried on both the general Products page, and on the Hawaii Info page.
Try the usual suggestions:
- Hit Refresh (usually F5 on the browser)
- If that doesn't work, clear your browser cache, restart it and try again
- If that doesn't work, remove all cookies from mediafire.com, restart the browser and try again
