Thank you for the welcome.
Zoran: Nope. There were no changes, except the purchase of a new e-book that I was trying to add to my kobo.
Dmac: Thanks for the suggestion. That's what I had to end up doing in the end. What a pain, but at least the books are finally back on my kobo.
I hope Kobo will be fixing these issues. As much as I love my kobo (I didn't have any issues with it until now) I was ready to chuck it out the window today.
