I'll say it again, but in all the back and forth with Ectaco, I've never had to supply any type of invoice/receipt for my unit to get anything done. They know when the unit was shipped out from their distributor by the serial number, and that should be enough to say if it's in warranty or not.
I would try to contact someone in tech-support directly, I've had very good response from Pavel & Phil:

As for removing DRM, took all of 30 minutes for me to get all the software and scripts for removing DRM from all the sites I use (from my library, to B&N, to Adobe ADE, etc). It's not very difficult, and makes it much easier to work with my books (I can convert them to other formats like FB2, which the Jetbook will pull the metadata from for the title/author, unlike epub). Tech support isn't going to be able to help with DRM or removal on the Jetbook until they release firmware that is DRM enabled for it.
I agree with the txt'ing comment, and while it really bugs me when I get a txt from one of our kids, I'll also say that internet forums have stunted the younger generation in their word & vocabulary usage. Just go to any gamer site, and I'd bet you'd go into bad grammer/spelling overload. (Look of leet or 7337 speak if you don't know what I mean, that stuff REALLY bugs me).
