I have a conversion problem I think...
I have latest Calibre version, plus Tools 4.8 from another place, which are cleansing excellently .
However, I cannot get two books onto either an Opus or a T1.
Each time, the "jobs" gets stuck on 67%, and when I give up and cancel, tells me it is unable to load due to no available format.
Both books, looking on book details, are MOBI.
Both come from the same supplier, and, umm.... arrived in my K4PC.
[ Other books from the same source, but not MOBI, have transferred OK. ]
Can any one help please.
(My tech skills and knowledge of terminology are.... patchy, so please don't hesitate to treat me like a 5 year-old .
