Order data missing when WPML Plugin is installed

Hi there,
I am using WPML to use Multilingual site. When the plugin self has been installed well, my order data (i am using woocommerce) are missing. I don’t know why. I’ve tried to reinstall the wordpress framework (included the theme i used before) , but it still shows me that it’s error. Please anyone can give me a solution? I need a help.

Your reply is my honor.

Best Regards

Oda Nicola
