[1.5.1] Fatal Error while Installing

It was a fresh installation of piwik 1.5.1

I uploaded all files via FileZilla
When I first browsed piwik directory, Installer gave me error to give write permissions on “temp” folder, after I did that it gave me following error:

Fatal error: Class ‘Zend_Config_Ini’ not found in /var/www/vhosts/MYDOMAIN/piwik/core/Config.php on line 347

Any Idea, what’s wrong?
Please respond a.s.a.p,
Thanks

RESOLVED.

Re-uploaded with another (paid) ftp client in Binary Mode and now Installer is working.

Thank you i was the same problem… and you have resolve it for me, “bynary mode”

Thank you!
