language change

Hello, I just downloaded your plugin, which is awesome really… but the language issue is a real pain in the arse! I check out other support cases, and I did went to my wp_config.php file (the only one in my site, I already checked!) and added the line you said… but not luck, not even when I tried with different languages…. I went to the plugin directory and grab all the languages files, and just backed them up, and renamed the es_ES one to everyname on the directory so all the files are in spanish… still no luck 🙁 I know this must be a bummer to you, and I really sorry because I want to use your plugin, but WP don’t use the wplanguage tag on the file, at least in mine was not in there… There is anyway I can force the plugin to work in my desired language? both english or spanish are fine to me… Thanks and if you need any help please let me know, thanks.
