iBooks in Maverick will not open / download
Since upgrading to Mavericks yesterday, I cannot access the majority of my iBooks on my Mac. I can see that the majorioty of my iBooks are showing in my iTunes library under iTunes/iBooks.
All barring 5 books have a cloud symbol in the top right of the books. When I click on the book to read the download symbol appears & the progress bar across the bottom of the book moves across & looks like its downloaded. But the book does not open. In the top right hand corner of the iBooks app is a download arrow, if i click on that it shows downloads available i.e. the book I am trying to read, but the open button is greyed out & nothing happens if I click on it.
If i go into the iBooks store and click on purchases it show sthat i have no purchased books to download, but when i click on the All tab it shows all my books, but when i try and click on one it opens up teh page & there is a read button. When i click on read, you can see it attempting to download and again In the top right hand corner of the iBooks app is a download arrow, if i click on that it shows downloads available i.e. the book i am trying to read, but the open button is greyed out & nothing happens if I click on it.
I have tried transfering purchases from my iPhone & iPad (as all my books on on both) and this hasnt doene anything. Ive tried signing in & out & thats donew nothing. In fact 4 books are missing from my physical library & everytimne i try and download from iBooks it states download failed, tray again and check available downloads from iBooks store, but when i do this is says i have no books to download.
Is there any way i can complete trash the iBooks library file, so that it will rebuild itself from the actual files on my Hard disc. I have been able to do this with iTunes before.
Basically the App is useless to me as i cannot ready 95% of my iBooks.
