Since getting SlingBox(HD Pro for Windows), I've been able to click on either a remote or the Guide Channel I want. No problem. Until yesterday, when SlingBox suddenly decided to keep me locked into one cable channel. No matter what I pressed, I can't get any of the other 150 channels.
What to do?

Is it possible that you're tuned into an unconfigured video source? Or perhaps the remote profile got accidently delted from the Slingbox. You might try reconfiguring the video source to refresh the remote profile on the Slingbox to see if this article (https://community.sling.com/thread/3300) helps.
