Hi there,
I've used Calibre a few times to convert from .mobi to .epub, without any particular difficulties. This time it won't work properly for two books I've just tried, here's the problem:
The epub works perfectly well in Calibre itself
On my ereader neither book will open past the first chapter. Instead the device seems to crash and needs to reopen.
I've tried to send the files to both the main memory and the memory card - to no avail. Other books bought recently (as epubs) all work perfectly well.
The ereader is a Sony PRS650.
I'd be grateful if anyone can give me a hand, it's for work / study that I need the books, and of course I've paid for them properly, and the conversion is for my own use.
