Warning, fatal error... Joomla 2.5

Hi all,
I have just installed chronoform on my joomla 2.5 site to check it out and already I have an issue unfortunately.
The error I am getting is:
Warning: require_once(/home/*****/public_html/administrator/components/com_chronoforms/versions/j2.5/admin.chronoforms.php) [function.require-once]: failed to open stream: No such file or directory in /home/*****/public_html/administrator/components/com_chronoforms/admin.chronoforms.php on line 19

What on earth..?

Thank you Bob. How embarrassing...

Hi again Bob, I have just made sure that the right version, I have v5, but when installing the tcpdf.zip it says
JInstaller: :Install: Cannot find XML setup file
