You need to update your files manually.
Look at the website instead of rushing on all the time, It never helps and make's you post a useless thread.
First off all -
Turn off your Anti virus, or disable, What ever.
May sound Fishy, but your anti virus, and many, even mine, avast <--- **** the Apostrophes, deletes it think it's a virus, but it isn't.
Download all the files Seperatly here - http://fgunz.net/gunzweb/gunzupdate/
Place them inside you FGunZ Folder, And replace them with what's already there.
Important:
Open up your Anti-Virus and put in the GunZ Folder or Just GunZ.exe in its Exception list.
If you don't know how to do this.
Google [Your anti virus] Exception list.
Hoped it helps!
Goodluck.
