According to vBulletin.org you have not downloaded this mod - if you grabbed it from our site, it'd be best to ask for support there
Our site is also the place for Priority support for both Lite and Pro versions, we don't keep up to date with vb.org support threads as often as we do threads on DBTech
That being said, if you link me to your site I can verify if the files are indeed in the correct location.
Please also post the exact error message you're receiving.
