[BookLoverToo]

I bought the latest Diana Gabaldon book from Shortcovers.com in epub, and try to read it in Calibre. When trying to view, the following error comes up. DRM-disinfecting software also produces the same error. Does anyone know what the root cause of this is (in non-developer English please - I don't fully understand the error message) and if it can be fixed?

Interestingly, ADE and my Sony can open and read the file just fine.

The error is:
Traceback (most recent call last):
File "/Applications/calibre.app/Contents/console.app/Contents/Resources/lib/python2.6/site-packages.zip/calibre/gui2/viewer/main.py", line 59, in run

Thanks for your help.
