[Help Needed] Calibre IOError: [Errno 13]

[Kyrylys]

Hi!

I´ve been using calibre since a few years and everything was ok but a few days ago everytime i run an unpdater for my library shows this error:

IOError: [Errno 13] El archivo está abierto en otro proceso / the file is opened by another process (sorry, mi SO lenguaje is set in spanish)

It occurs with different ebooks ramdomly. I have none of them opened or any other program running.

I tried to unninstall and reinstall and does nothing, plus when i did it it was like i did nothing because my libraries and my settings were the same. Even i clean the windows register. (O_O)

SO Version: Windows 7
Calibre: 3.6
Full error:

calibre, version 3.6.0
ERROR: Excepción no considerada: <b>IOError</b>:[Errno 13] El archivo está abierto en otro proceso: u'd:\\biblioteca 50k\\t. s. eliot\\asesinato en la catedral (65448)\\cover.jpg'

Please, note again that the ebook is not the problem, it shows different books at different % but i noticed that always is ebookx\\cover.jpg where the error shows.
What can i do?
Thank you so much.

THat error is coming from the Actualizador Biblioteca EPG plugin. Try disabling/uninstalling that and see if the error goes away.

I need that plugin to do the updates, i can´t disable it! xD
Well, i´ll try to reinstall it again. i´ve tried to unistall/reinstall calibre, but i didn´t thougth od do it with the pluging. thank you!

Edit. Sounded too good, the problem persists after reinstall the plugin.

I made the libary again in another path and seems working fine.

Mystery…
