Cannot open Multiterm - impostazioni cultura and global plug-in

I'm trying to open Multiterm 2014 and there's an error "An unexpected error has occurred while loading the global plug-in services". if I click ok, it then says "Impossibile trovare nel disco risorse appropriate per le impostazioni cultura specificate (o per le impostazioni cultura non associate ad alcun paese). basename: Sdl.MultiTerm.Studio.Catalogue.plugin" what am I supposed to do to open Multiterm? thank you for your time!
