Message: <blockquote data-quote="RCanning" data-source="post: 1588101" data-attributes="member: 18344">DRM files don't work on multiple machines.OK.I signed up with DriveThru and downloaded a free product.I was able to use it and back it up for use on my Powerbook without a problem. It worked almost like a normal PDF.I then got my wife to take the PDF to her work and try to open it to see if she could print it (my work does not use Acrobat Reader 6, hers does). When trying to open it there were problems with the Adobe ID authentication, but we eventaully got through that and had Adobe reporting that I was logged in.We then tried to open the PDF, and no matter what we did, it kept reporting "Bad Encypt Dictionary". Basically, even when logged in to Adobe, the PDF did not work.My wife is a print specialist and trained to use Adobe Acrobat, and with 15 minutes of playing around, she could not get the thing to open. She is using WinXP and Acrobat Reader 6. It just does not work.I can easily break the DRM on the Powerbook using the "Save as PDF" feature, but I would prefer not to have to do this in order to print any material I might purchase. There is a quality drop and that is just plain bad.The limits to copy are annoying, and I personally think that they should be able to unlock any material in the PDF that is OGC; but I can live with that.Not being able to put the file onto another machine, even when I am logged in, is just plain wrong.DRM does not work the way they indicate. You can not open the file on another computer when you have logged in. Tried twice on two different machines running two different OSes (Win XP and OS X), it failed both times.Richard CanningUpdate: I have sent them a message using their Contact form asking for them to explain what is going on. Adobe has no mention of this problem, and I know it is logging into Adobe correctly because the machines are being re-directed to DriveThruRPG when we try to open the file. It looks like DriveThru are the cause of the problem.Update 2: In responce to my query about this Adobe pointed me to the statement on their <a href="http://www.adobe.com/support/techdocs/30f36.htm" target="_blank">eBook FAQ page</a> which states...I was told flat out that if I download DRM protected files on one computer, I will not be able to load them on another. I know this contradicts what DriveThru are saying, and what other people have stated, but this is according to Adobe.They also pointed out that...So someone is flat out lying about DRM. I wonder who.</blockquote>
