I'm well aware of Tunebite's capability and its core function. My hope was that by installing the program it would overwrite my systems DRM files and make things "healthy." Clearly I was wrong.
It appears even "RealNetworks Technical Support, Tier 2 Escalation Department" are unable to give me a resolution. Their response was: It clearly indicates that some of the registry files been corrupted in your computer and this is the reason, you are still prompted to enter the username and the password, even if you have signed into Adminstrator account. I am sure that Windows DRM will be available even if Rhapsody has not been installed. In this case, please contact the System Manufacturer to assist further.
Ah the sweet smell of pass the buck.
Well still nowhere near an answer as to how or why my DRM files are corrupt or gone.
