When I try to install the component I get the message "successfully installed" but when you click on any area of ​​the component, either in the flap extensions, or any icon that appears upon instalção ... the message that prayer is:

Fatal error: Class 'JViewLegacy' not found in / home/a4836184/public_html/components/com_hotspots/views/view.php on line 31

I've tried to create a menu for the component .. but also appears this same error, i do not have access to any part of component ... I've tried installing multiple versions labels available and nothing happens

what should I do?
