Hi I'm a newbie to Calibre but not computers.
Problem - I put my library on my external disk then by accident I plugged in my eBook without switching on the external disk. Windows 7 then changed the drive letter of the ext disk from G to F. Now Calibre won't run 'cos it says it can't find the library at G! How do I either change the drive letter or get Calibre to recognise the library at F or start another library?
