you need to either:

A) install the language files it gave you

B) re-upload the language files because they uploaded incorrectly.

im not sure what the case is on the user info block, but many times mods will include a file called lang-english.txt . this means you must open the .txt file and copy the language components into the lang-english.php that it specifies.

for example: you download the mod package and it has its directory already set up so that all you need to do is select all and upload. say there is a lang-english.txt in your download package, and its path is admin/language/lang-english.txt . you must open admin/language/lang-english.php and copy the components from the .txt file to the .php file, then reupload.

yeah i went in depth on this one but that way this can be am FAQ for future problems
