Downloading paid plugin

I just purchased a plugin from the marketplace and tried to synchronize my project and install it but it is failing due to a requirement for the version 1 Translate plugin and I have version 2 installed. Is there a way for me to download the plugin directly and see about modifying it to work with the newer version? The plugin is no longer supported and I didn’t realize it’s last ‘supported’ version was for OCMS 2.0, my fault. If there is no way to download it, is there a refund policy that anyone has tried for this scenario or am I just out on this one?
