Doranna, unfortunately this sort of thing has happened to a lot of people. I am afraid it is a but of an uphill battle for readers sometimes
This is why imho it is totally the right thing you guys are doing in taking control of your backlist books and putting out the ebooks yourselves, so that you can treat the readers fairly. Bear in mind that a lot of us here are the diehards so we may not represent the average person on the street, but by fair the dominant mood seems to be that people are quite happy to pay a fair price for DRM-free titles from authors who treat us right
Fwiw the last two times I wrote to an author about such an issue, one was to a big-name author and I got no reply and the other was to Joe Haldeman and his wife personally emailed me a copy of the book off her own hard drive
