I am running Magento 1.4.2 and I need to get LinkPoint/First Data to work. I am trying to rework this module : [url removed, login to view]
I know this extension is not compatible and I have been trying to get it to work but had no luck. I need to get this module updated to work with my store.
I would like to update Magento to the latest version so I would like to have this module work with the latest version.
