I keep getting this fatal error. I tried installing it on the normal way and by uploading it into the tmp files but neither way works.
Can you help me out so I can test everything out on my own website instead on the demo site before buying the product?

Fatal error: Cannot access protected property JInstallerComponent::$manifest in /home/....../domains/....../public_html/administrator/components/com_booking/install.booking.php on line 98

Common !

It's been long enough without an answer ...

Or some one helps me, or I don't buy this product ...
