I was able tofix your module by making manual edits to include my database info.
Also, you have the default table prefix as vb and it is usually always vb_. So people will get an error with the prefix set as vb only.
I fixed your file this way:
1. I had to comment out
//$database
//$username
//$password
2. I had to manually edit and input my database info like this:
Code:
$link = mysql_connect ("xxxx.perfora.net", "dbxxxxxxxx", "pwxxxxx") or die("I cannot connect to the database");
mysql_select_db ("dbxxxxxxx");
Now that I manually edited your file it works fine. I believe you have a number of errors in your current zip file.
