Second ASA5510 for development work

Question

Up to now we've been making configuration changes to a production unit.  Not such a good idea.
We just bought a second ASA5510 to be used as a test unit but we're having trouble getting past the install of ASDM.  We used the console interface to reset the unit to factory settings and then we followed the Cisco Getting started guide. 
We are connected to the management port using a crossover cable (per the instructions) and we opened a web browser to the following url (again... per the instructions) https://192.168.1.1/admin   As expected we receive a certificate warning that we are instructed to ignore.  We click on continue and we receive the dreaded "Unable to Launch Device Manager from 192.168.1.1" and the only option is to hit OK.
I realize its not much to go on, but that's all we've got.  We can connect using the Console port and execute commands but at this point we would prefer using the ASDM.  I'm assuming the ASDM image is either not on the disk in the ASA of if it is there is something wrong with it.
Yes we enable HTTP on the management port.
Any ideas/suggestions would be greatly appreciated.
