Under oscommerce admin, tools, version checker, I am running 2.3.1. Heres my output. Version Checker
Installed Version: osCommerce Online Merchant v2.3.1
This appears to not be the problem. I downloaded a language pack that I found here (traducao_oscommerce_2.3.1_v.1.1), but have not executed SQL statements because it appears after installing and uninstalling multiple times that I compound a problem that already exist. So, as a result, I have maually placed the portugues.php and language folders where they belong and here I am. Is there any other options that may be available? Your assistance is appreciated.
