[SOLVED]Error installing last release 2.1.1

Hi,
I saw there is a new version and when i tried to update the component it doesnt install at all. The update procees freeze at some time given some blank screens and or not xml found.

This is an error that gave me on one of the hosts i tried but finally it seems that it was updated anyway.

Fatal error: Call to undefined method FOFPlatformJoomla::clearCache() in /home/public_html/testjoomla25/tmp/install_51faf446e9feb/script.com_tracktime.php on line 99

I tried two hosting providers and also my own local server with no success

Is it just me or little bug on the release package??

Thank you

there was a bug in the installation package.
please download the latest version.

it seems that the Joomla behaviour of creating bugged release infected us as well

Same for me, and after installing the lastest version : il works fine.
