Stock Module

I have installed the Stock and Stock API modules. They dont appear to be working (specifically the stock module). I get the following error.

warning: Missing argument 1 for drupal_get_form() in E:\****\***\********\includes\form.inc on line 69.
warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, '' was given in E:\****\***\***********\includes\form.inc on line 366.

The asterisks are replacing the folder names where my instance of Drupal is installed.

This is all on a test web site which is part of an internal network. Some things wont work on this test web site because of the proxy server which is blocking it. Do you think that is why the Stock module is not working?
