“Restricted Access” after succcessful install?

I successfully installed WordPress for Joomla on my site (www.imnotcartman.com) …ok, ALMOST successful …it said it couldn’t find one of the .gif images – no big deal.

I have the JD WordPress on my Components menu now …when I click on it, I get “Restricted Access”. That’s it! I’m lost.

When I go to my main site as a user and click on “JD WordPress” on the main menu, I get the following:

An error has occurred
Error: No input to read has been passed. in /home/cartman/public_html/cms/libraries/joomla/document/document.php on line 448

I’m new to Joomla (very new), but I did do a search in the support forums first before posting.

If this is a simple fix, I would appreciate anyone’s guidance. So far, this Joomla CMS is NOT turning out to be as great as it was touted.

Anyway, thanks in advance!
