GTranslate Wordpress 3.0.4 - Error Line 39

[[email protected]]

Hello.

I used to use GTranslate while i was building my
website for my trip from Buenos Aires to Alaska.
www.huellasdeamerica.com

I updated Wordpress and it stopped working.
I am having this error while trying to activate it.

Fatal error: Undefined class name 'self' in /home/jy000302/public_html/wp-content/plugins/gtranslate/gtranslate.php on line 39

Please id like to know how to solve this.
I use the free version.

Thanks a lot
Peace.
