Error in Admin / Joomla 3.3.3

Dear Forum,
I made today an update to Joomla 3.3.3.
When calling Chrono form (Version I know, unfortunately, no longer) comes the following error message:

Warning: require_once(/var/www/web626/html/www/mlconcept/administrator/components/com_chronoforms/versions/j3.3/admin.chronoforms.php) [function.require-once]: failed to open stream: No such file or directory in /var/www/web626/html/www/mlconcept/administrator/components/com_chronoforms/admin.chronoforms.php on line 19

Fatal error: require_once() [function.require]: Failed opening required '/var/www/web626/html/www/mlconcept/administrator/components/com_chronoforms/versions/j3.3/admin.chronoforms.php' (include_path='.:/usr/share/php:/usr/share/pear') in /var/www/web626/html/www/mlconcept/administrator/components/com_chronoforms/admin.chronoforms.php on line 19

Why is that?
Ask for your help, thank you!

Hi Max,
thanks for the reply.

Then lose its existing forms?
So, you mean just install "over it"?

Thanks for your answer !!

Hi activewebs,

Just install the new version using the Joomla extension installer. Your forms will be kept. Though for safety you might want to Export a backup copy and/or backup the database tables first.
