At the very moment this person was writing this comment, I was on the telephone with the Adobe folks thinking that the problem was my upgrade to Adobe Professional 8 from Adobe Professional 7. (I also own Adobe Standard 6.)
After spending almost two hours on the telephone, being cut off and transfered to at least seven customer service persons, blah, blah, blah the last person informed me that the reason no one at Adobe could help me was because I never stated what the problem was, i.e., that I wanted to read an ebook that I owned and that I previously could read with Adobe software!!!!!
When I told this idiot that he was insane as those were the very first words out of my mouth with each new person, he informed me that it was Amazon's fault.
I have two other applications that can read PDFs as long as they are not electronic editions purchase in the Adobe format, so:
FROM NOW ON, IF I WANT TO HAVE A DIGITAL BOOK ON MY COMPUTER I WILL PURCHASE A PAPER BOOK, RIP IT APART, SCAN IT, RECYCLE THE PAPER, MAKE A CD OF IT, AND READ IT OFF MY HARD DRIVE WITH AN APPLICATION OTHER THAN ADOBE.
I don't know what I resent more: having to repurchase books I already own or the fact that the two hours I spent with the Adobe folks is two hours I will never have again. Jeez, why don't they just say, "hey we changed the rules and now your ebooks are no good"?
