My b2evolution Version: Not Entered

I cannot add any widgets to Beta 2.2. I have no idea what's wrong. I tried re uploading via someone's suggestion, no luck. What can I do to fix these problems?

I get this error when I try to add any widget to a blog in any situation:

Warning: load_class(/home/trekdenlife/public_html/blogs/inc/widgets/widgets/_free_html?ctrl=widgets.widget.php) [function.load-class]: failed to open stream: No such file or directory in /home/trekdenlife/public_html/blogs/inc/_core/_class4.funcs.php on line 40
