cant export CSV file - fatal error

While trying to export my data to CSV file I receive the following error?

Fatal error: Class 'JArchive' not found in /home/sbjane/public_html/administrator/components/com_osproperty/classes/csvexport.php on line 128
Did anyone already face such issue and knows how to overcome it.

A propos, does anyone know where physically the OS data is saved.

Hi Lusok,
Please download OS Property (2.6.1) (uploaded today) to get this issue fixed
Thanks

Hello,

Can you please send me the link when I can download the new version 2.6.1 without additional payment.

After uploading the new version of csvexport.php and scvexport.html.php I am getting same problem:
Fatal error: Class 'JArchive' not found in /home/sbjane/public_html/administrator/components/com_osproperty/classes/csvexport.php on line 128.
How to resolve it, without to replace all component and not to lose all changes that I already did for my site?
