Using CodeIgniter with phpDesigner 8

[eluser]php_princess[/eluser]
If I do phpInfo(); inside of phpDesigner8 it says xdebug support is enabled and I have version 2.2.2

I'm able to use CI's sessions just fine on the remote host.

My host allows remote database connections and I am to connect with my local copy of phpMyAdmin.

I'm confused if I truly have xdebug. I just did the following:

-Opened CodeIgniter's index.php in phpDesigner8
-HIt the Debug button (its right of Code button)
-Selection option that says Debug F9
-Got a prompt that says "Do you want to break on first line?"
-I clicked yes.
-It highlighted the first line of index.php in blue
-I hit F9.
-The code window was replaced with an error that said something about the maximum execution time of 0 being exceeded and something about not being able to find PHP and xdebug.

If I repeat the process, the outcome varies. Sometimes after the "Do you want to break on first line?" prompt, the window still goes blank but the error is just "Disallowed Key Characters" Other times, I get the maximum execution and not being able to find error except it's in a prompt.
