DRM Calibre Plugin stopped working

Hi Everyone,

Not sure if I should be asking about Apprentice Alf's plugin here, but I'll chance it if that's okay :D

This plugin has been working great - but yesterday it appears to have stopped.

I did update Calibre this weekend to the 1.15 - could this have made a difference?

Do you think I should delete the plugin and reinstall?

I know I can mess about and try, but I'd really like to find any answers first.

Thanks for your help :xmas:

BTW - Windows 7
