Events Manager vs. Godaddy hosting: “headers already sent” errors

Greetings everyone!

I have a WP site using Events Manager. Hosting is by Godaddy.

Godaddy over the Holiday moved my site to a new server and set permissions to 705. I had to reset my directors and files to 755 for directories and 644 for files. My site is back up, however. Events Manager when activated gives header and footer errors. Here is the header error:

Warning: session_start() [function.session-start]: open(/var/chroot/home/content/81/5826381/tmp/sess_o5tim88mbjktilehv9ucioa521, O_RDWR) failed: No such file or directory (2) in /home/content/81/5826381/html/BurbankBaseball/wpdemo/wp-content/plugins/events-manager/classes/em-notices.php on line 11

I called Godaddy and they said permissions changes were up to me. They said permission changes were up to me.

Does anyone have an idea how to restore Event Manager? Any insight would be appreciated!

Cheers!
