Solve small problems with script

I own a scrip that have a couple of small problems that won't take long to fix. The first one is the language pack; because this script was translated from English to Spanish the script won't accept the updates and writes the words as Contáctenos, Regístrate instead of Contáctenos, Regístrate, etc. The second one I need to disable the payment link; when you list an item or when you activate your eShop (store) it will take you to payment before is listed or activated; these links need to be disable. I need a step by step how is done on both cases. If we agree on the price I will give you the Username and Password for both the actual website account and the the hosting where all files are located. You can log on to [login to view URL] see the website and the problems that I am talking about. Regards, Julio
