I've had my Arc for about two weeks now and have been busily trying out different reading programs. I have a lot of Ebook.Com books so downloaded them to some software it provided, Blue Fire I think. I then discovered that there is an app for Ebook.Com and afer I logged in it gave me the automatic option of downloading all my books again, which I did.
One book on the Books on Board site I couldn't download as it was no longer available in the uk site so I was feeling quite smug yesterday when I found another app, Aldiko, which allowed me to register with Adobe and I am now able to read the book.
When I first opened up I was asked to download another load of updates to the Arc, which it did and then rebooted. I was going backwards and forwards between the reading apps to decide which one I liked best. There was a problem with the Ebooks one and I found I could only see the first page, the same thing happened with the Blue Fire but Kobo and Kindle were fine.
Bit long winded but this is my first android, is it like windows, if something causes problems do you just remove the software and reload it again.
