GeoIP | error fixing previous reports

Hi,

I am running Piwik 1.0 without GeoIP and today decided to install this plug-in.

It is working well but it I was not able to update the previous visits in the database.

Running geoipUpdateRows.php from the browser, it only updates the last record and it displays the following:

Zend_Session::start() - /home/monitor/libs/Zend/Session.php(Line:480):
Error #2 session_start() [function.session-start]: open(/session/tmp/sess_5ce5aa0aa80738c247ecad5a3f9acef5, O_RDWR) failed: No such file or directory (2) Array /home/monitor/libs/Zend/Session.php(Line:490):
Error #2 session_write_close() [function.session-write-close]: open(/session/tmp/sess_5ce5aa0aa80738c247ecad5a3f9acef5, O_RDWR) failed: No such file or directory (2) Array /home/monitor/libs/Zend/Session.php(Line:490):
Error #2 session_write_close() [function.session-write-close]: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/session/tmp) Array

/session/tmp/ is 777

Any idea to solve this problem?
