I had been using the free version of Express Scribe with a VEC foot pedal. It stopped working last week, and I was prompted to buy a license. The NCH website seems to indicate that my pedal is no longer supported by the free version. The "Buy Software" page shows a Basic version and a Professional version. Both cost money. Where can I find documentation of the differences between these two versions? Will they both support my foot pedal? Other than the "Buy" page, the various pages of the NCH site discuss only the Free and Pro versions, not the (both paid) Basic and Professional versions. Thanks for any help.
