I was having problems with this too. I just got it to work.
1. Create a file with the following contents:
Content visible to verified customers only.
2. Save it as reviews-module.php or something like that.
3. Upload it to the /forum/modules folder.
4. Create a Module in vBadadvanced admin using PHP File.
5. Fill in the title and where you want the module to appear.
6. Choose the file you uploaded above from the drop down menu.
7. Make sure you check Yes for Clean output.
You should be able to leave everything else as the defaults.
Don't forget to set how many columns and reviews you want displayed in inc_reviews.php.
