ValueError

[vikischeldrup]

This error comes up every! time I am trying to save to disk. I haven't been able to find an answer I can understand by searching google and even here - please help? I just installed 2.13 and am thinking I should go back to an older build?

The current version of calibre is 2.15, update to that and you should be fine.
