Sometimes folders may look like they are empty but the file extension filters may just not be showing the real contents. If it truly is gone then it should not be hard to reinstall but I'm betting it's in there.
 
Anyway... good luck and if it doesn't work out you could always contact support and they'll sort ya out.
 
Cheers.
