Cannot import settings from All In One SEO plugin

Hi!

I have a serious issue whit this plugin. I have activated the plugin and I wanted to import settings from the perviously used (still activated) All In One SEO plugin, but whenever I have clicked on the “Do you want to import its settings?” exclamation on the top I have got an error: “You do not have sufficient permissions to access this page.”. I have tried to use SEO Data Transporter plugin to do the job, but there is no Yoast listed in the destinations list, so it is not a solution. I have tried switch themes, disabling other plugins, but the error did not go away. I must import All In One SEO data to Yoast, please help me to achieve this goal!
