Access Denied when trying to save imports

[tugpilotsmiffy]

Hi I'm using Editvoicepack 3.1 with fs2004, with windows 10I import files in the correct manner, then update, then when it comes to saving ork before exiting I click save, after a short while i get an access denied message, Editvoicepack continues to say saving in the bottom left hand corner, and I am unable to exit the programme without shutting my computer down, any ideas
