Has anyone had any joy with this? I'm am currently trialing the most current version of Dictate & Scribe. Both have the "Invalid email address" problem. I've emailed NCH no less than 5 times, and they simply don't reply. I am also running Windows 7 x64, and can confirm that under XP 32-bit the problem isn't evident It seems a real shame they can't at least have the decency to get back to me - we're potential buying customers, and think the product looks great save for this fault! If I just knew they were working on it, it would keep me interested, but otherwise this post is my last ditch effort to be heard and replied to.
