git fatal Could not read from remote repository

Question

I want to set git with http://danielmiessler.com/study/git/#website to manage my site. I am working using the git ming32 command line in win7:

$ git push website +master:refs/heads/master

Bill@***.com's password:

Connection closed by 198.91.80.3

fatal: Could not read from remote repository.


Please make sure you have the correct access rights

and the repository exists.

I am stuck here at the step in the instructions: git push website +master:refs/heads/master. I think the program is looking for Bill@***.com. when I connect via ssh to my site I have a different username. so maybe this should be abc@***.com. Can someone help me change this or  can I push it under an alias?
