Using the datastore in 3.6.4

[thincom2000]

I'm trying to use a datastore entry I created (the entry exists in the database in the datastore table) in a foreach() loop, but it tells me I have supplied an invalid argument for foreach()

Database record:
title = my_store
data = a:1:{i:1;s:6:"ITEM";}
unserialize = 1

PHP Code:

$vbulletin->my_store = unserialize($vbulletin->my_store);
$store = $vbulletin->mystore;

foreach ($store AS $s)
{
         $my_new_array[] = $s;
} 


I've looked at tons of other examples from products I have installed and it seems to work fine everywhere else...
