Joomla Free extensions

Dear,

I installed the Module and load it into my content page. But the following error is shown and page is blank.

Fatal error: Class 'JFile' not found in /kunden/139681_6900/sites/rhychi_j34/modules/mod_jo_facebookevents_pro/helper.php on line 115


And in Backend i got following errors:

Strict Standards: Only variables should be assigned by reference in /kunden/139681_6900/sites/rhychi_j34/modules/mod_jo_facebookevents_pro/elements/loginfb.php on line 25
