So I have Mandano premium, works fine with other epubs. I installed overdrive and downloaded Adobe epubs from my local library, and added my Adobe ADE account info in Mandano. But when I try to open the books downloaded from Overdrive in Mandano, it says cannot open the file. The books open fine in Overdrive.

Any idea why mandano cannot open these overdrive epub files, even though I entered my Adobe ADE account info?
