Phpunit Issues Ran Within Zend Studio 11

I am having an issue running PHPUnit tests within Zend Studio. Everything is up to date and PHPUnit itself runs normally on other projects. Running it against my Yii applications however, I receive a "Cannot launch PHPUnit tests ( port address 7478 ): Accept timed out." error. But, as I said, running other non-Yii tests everything functions as it should.

I do not know what files I should post to receive help on this issue. So, let me know what config files you would need to see, please.
