It could be that all of that modding is effecting it..
Did you make sure that you got the modified FH version from the thread where you got the Preset Sync from? Without out, I don't think it'll even work. You can also check to see if there's a 'badfile.reminder' and getting rid of the file that's causing the problem and then the folder itself.
But again, make sure you also gotten the modified FH version from that thread and ran it once the download is completely. Usually it replaces the desktop icon and you would have to click it.
Hopefully something works out for ya.
