How/What to install to get 6vC PayPal working

For days if not weeks now I have been struggling with a defective PayPal Module in that it deactivates itself a few minutes after it has been activated. Prior to this it was working like a Swiss clock for years.

Out of desperation and with no advice available, I have ripped everything out of the Modules section except for a php file called [B]functions.php[/B] (@version SVN: $Id: functions.php 25466 2010-02-01 14:12:07Z alfonsas $)

So in the Admin section, under Modules, I am starring at a blank area (see image)

So now I need help in selecting the right 6vC [B]PayPal Module[/B] and help in putting it into play with OXID CE version 4.6.4 because 6Vc works with this version.

Please help me.
