Thank you for checking this out!
Well, the reason for not upgrading to 10.4 is simple. It costs money that I don't have to spend.
10.3.9 runs great, and every other piece of software I have allow me to run the versions I have installed. They also run great. Only Digital Editions suddenly refuses to run, for no apparently good reason.
I use Digital Editions to read (time limited) ebooks I borrow at the library. I have not been able to read these with Acrobat Reader.
On a more angry note: I think software that on purpose renders itself useless is very near a kick in the face on the user.
Why can't users have the OPTION to upgrade, like with any other civilized software? Especially when it is obvious that the new version is incompatible with the machine's operating system.
