It seems to me that the AVS4You folks need some reminding what the term "Unlimited" means.
I bought AVS4You with the understanding that the product would be Unlimited use. That means I, not you, decide what computers it is installed on. I, not you, not EVER YOU, decide where and how it is installed.
You have been paid. If you want more money from me, step one is to act in an honorable and forthright manner. Offering me a $20 discount on software I've already paid for is not even close to that.
Now, I'm willing to meet you halfway. I don't need, want, or care about audio editing or playback and have never used those features. I've already paid you for an UNLIMITED license for my VIDEO editing software. Unlock it, keep it unlocked, and I'll delete the audio software. It makes a lot more sense for you to offer a la carte true unlimited licenses than for you to try to pretend that the word "unlimited" means something it doesn't.
I've attached a screenclip of the Dictionary.com definition of the word "Unlimited" to help you out. As long as you stay true to that definition, you may continue using that word in your advertisements. Stray outside the definition, and I promise you so help me god you'll be reported to every single consumer reports website on the web. I hope we're clear on that, because I have no intention of repeating myself.
I should not have to swear at your support staff via email before you do the right thing and give me access to my own software.
