Unable to login to the web interface of CSC SSM-10 Secuirity Module on my ASA 5510

I have a Cisco ASA 5510 with the ASA-SSM-CSC-10-K9 Security Services Module. I can successfully logon to the ASA from both the CLI and the ASDM. I can successfully logon to the CSC SSM-10 using the CLI interface & the ASDM.

I CANNOT logon to the CSC SSM-10 web management interface. I see the logon page with no problems however when I enter my CSC SSM-10 password (which works fine from the CLI and the ASDM) it simply returns to the logon page as if I have entered an incorrect password. My understanding is that the CSC SSM-10 password should be the same whether I'm using the CLI, ASDM or web management interface. My subscription has expired however I should still be able to use the device with the knowledge that signatures will not be updated.

As a side note the CSC SSM-10 module is displaying some odd behavior. When I change a value in the CSC SSM-10 module using the CLI OR the ASDM I can successfully enter new values but then when I refresh the interface the old values are still there. This is the output that I am seeing:
