buying this module, and not working from the beginning, and seems it's very difficult to have new update or correction, the module was installed same i download, but in 1.6 - to latest 1.6.19 it's doesn't work correctly, no support, no update from the latest i buy v2.5.4 . so this module still not working and made bugs many bugs also if you try to instal bonus, the better is to wait and hope maybe it will be update that can be resolve the problems. or as i do actually, uninstall and said ok no more buy there.
