It seems that you are having some issues with the SlingPlayer since it does not seem to recognize your password. If you have updated the password information, the issue might be related to the browser in use.

Thanks but this does not help my situation. I am currently using the Firefox 4 browser.
My issue is that after setting up my slingbox at home, viewing the streaming video, and setting my password, I am not able to view the video stream remotely as the slingplayer is telling me that my password is not correct. I don't understand how I am able to log into my account to make this comment, but am not able to watch my slingbox supposedly due to an incorrect password.
