I used your plugin not so long ago to upgrade from an earlier wordpress version to version 3.4.2. It was awesome because i've had serious problems before to update on my sftp connection.
Now i'm trying to update from 3.4.2 to the most recent wordpress version but i'm suprised to see that i keep on getting another error. I haven't changed a thing on FTP settings or whatsoever since my last upgrade with this plugin.
Can you suggest a solution for my problem? I'd prefer not to upgrade manually if not needed.
In addition the error message i keep on getting now:
Downloading update from http://nl.wordpress.org/wordpress-3.5.1-nl_NL.zip…
