Major errors after installing plugin

After installing the plugin, in my dashboard at the top I have the following errors:

Warning: file_get_contents(https://api.wordlift.it:25062/api/site) [function.file-get-contents]: failed to open stream: Connection refused in /home/ajcr3656/public_html/ajcrmedia.com/wp-content/plugins/wordlift/php/insideout/wordlift/services/ActivationService.php on line 27

NULL

I am able to go into the plugin’s control panel and try to sign in with facebook or twitter, but both fail. If I register directly with wordlift, it says it worked but then it doesn’t.

Maybe this is a permissions error? My plugins folder is set to 755 and so is the wordlift folder.

Any solutions?

Thank you,
AJ
