Sometimes it's a combination of software, I never had problems with editvoicepack untill i used it together with aiseparation. it went wrong always
during approach. Removed EVP and no problems but like you, i wanted to use it so removed aiseparation and replaced it with aismooth and now it runs
fine, both evp and aismooth. It might be diffrerent on other pc's of course but check what else is running and see if the cause might be in there
