How to change language

Hello,

I downloaded and installed Sweet Captcha in the wrong language.

I didn’t find a way to change the language. So I uninstalled it, installed again, but this time I wasn’t offered the chance to select the language. I understand it kept the preferences somewhere when it was uninstalled.

How can I change the language now?

Thanks
