Cisco ASA 5510 unable to connect using ASDM

I can't connect to my ASA 5510 using the ASDM Launcher or by connecting to https://192.168.1.1. I have little experience working with Cisco appliances so I was relying heavily on the ASDM Launcher to work through the initial configuration. I'm waiting on approval for a training class.

Ideally I would like to reset/restore/recover the ASA 5510 to its factory out-of-the-box settings. I was able to connect using ASDM Launcher at one time, but I must have mangled the settings somehow which is preventing me from connecting through ASDM.

I've done extensive web searching and found many articles that suggest using the configure factory-default command, which I have done, but still can't connect using ASDM Launcher.

I CAN connect and issue commands from the CLI using the blue Console cable and HyperTerminal, but I lack the skills to troubleshoot and identify the problem from the CLI.

Symptoms:

When I attempt to connect using the ASDM Launcher or https://192.168.1.1 the messages "Contacting the device," "Loading cached software" and "Software update completed" are visible, but I just receive an hour-glass that never goes away and I can't get past the logon screen.

When I try the "Run in Demo Mode" option I receive the following error: "ASDM did not get a response from the ASA in the last 60 seconds. Please check the configuration and your connection and then try again by clicking Refresh."

While in Demo Mode there are two devices (192.168.1.1 & localhost:55000) in the Device List on the left, but I receive the error above when I try to connect to them.
