VehicleManager component support

I am interested in setting up a Car Rental website. Have downloa paded the latest Basic version to evaluate. The component does NOT install right:

- It says --> Installation: succesful
- But says --> XML Parsing Error at 1:30.
Error 18: unknown encoding

I have Joomla 1.5.9 version.

Trying to visit the Vehiclemanager page, I get the below error.

_____________________________________________
Fatal error: Cannot redeclare showitem() (previously declared in /components/com_vehiclemanager/vehiclemanager.php:590)
in /templates/rt_meridian_j15/html/mod_roknavmenu/default.php on line 12

Hi,

XML Parsing Error at 1:30.
Error 18: unknown encoding
That not error - that warning. Why it appears - don't know. (We did big
research)

Cannot redeclare showitem()
Please download last version from OrdaSoft.com

Thanks
