I had vbpets installed on rc3 before i upgraded to rc4 and it worked fine on both of em. You could try running through the instructions again, make sure you create the extra pet coloumns into the user tables (to do this you'll need permission to run queries from within your admin cp, you can do this by editing your config.php file). You'll also have to create the actual pets template yourself (this is the table that displays your pets name and picture etc on your members posts) by editing your forums style.

These are the main bits that i reckon peeps will get stuck on or forget..
