I can't really help you with getting your game register but that's all the suggestions I have for your error: http://sims3.crinrict.com/en/2011/03/error-cyclic-redundancy-check.html
You do have the option to chat and pressed the button to start the chat right and the chat windows also opens there's just no advisor ?
Unfortunately I've already gone through your document for it, I was hoping to get some other suggestions by posting on here.
When the chat window opens, it says the standard "please wait while we connect you to an advisor" or whatever, and i never get connected to one.
