Dear,
Need add many changes to component.
so: Please do update of the component to last version.
You must have version of component not lower 3.5 to make update.
Before making any upgrades, make the backup files of site and DataBase
At first please check upgrade/update process at the test website!
If you have custom changes of component, you can lose your changes.
Please, in that case do not make update.
If you would like any further information, please do not hesitate to contact us too.
Regards
