I open gunz normally, and leave it for a while (last night an hour) and it justs stays on 0%. Last time i had gunz it did this but it worked after a bit.
I've tried Gunzfactor and downloaded the IGunz fixed thing and i double click gunz on that and it pops up with "This application has failed to start because fmod.dll was not found. Re-installing the application may fix this problem."
I've re-installed about 5 times and it hasn't worked...
