It seems that you are having some issues with the SlingPlayer software since you are not able to log in automatically.
I recommend you to log in as you normally do. Whenever you close the SlingPlayer 2.0 version, make sure to use the "X" on the upper right-hand side corner (without login out) and then open the connection one more time. This process should allow you to keep the connection without entering all the required information.
If the issue persists, I recommend you to stop using the no longer supported SlingPlayer 2.0 version and use the web-based application through www.slingbox.com.
Make sure to follow these indications and let us know how it works for you.
