I understand you are having difficulties connecting to your Slingbox since the newest SlingPlayer plugin update. The first thing you will want to check is whether or not you system meets the minimum system requirements, also make sure that the version of Internet Explorer you are using is 32-bit. If you are still experiencing any issues, make sure that your Java Script and Adobe Flash are up-to-date.
Hope this helps!
