Hi I had the same problem and this is what I did to get it to start working again.. This is not my work but I found the info from another source.
Login to the box using you favourite SFTP program, I use WINSCP
Navigate to /private/var/mobile/Library/Preferences/XBMC/addons/plugin.video.icefilms/mega
rename the file: megaroutines.py to something else like megaroutinesold.py
download the new megaroutines.py file from here: http://anarchintosh-projects.googlecode ... 5524300082
place that in the folder we renamed the old file and reboot apple TV it should hopefully now be working.
PLEASE REMEMBER TO RENAME THE OLD FILE AND EVEN TAKE A BACKUP COPY OF IT TO YOUR PC or MAC
