You didnt mention your Roku model # and firmware version: Settings/System/About
If what @DBDukes doesnt work, then try the following
1) Check for updates (Settings/System/System updates/Check now) - try again
2) Change your Theme to the Roku Default (Settings/Theme/Restore default theme) - try again
3) Change your Screensaver to a Roku clock (Settings/Theme/Screensavers) - try again
4) Network connection reset (Settings/System/Advanced system settings) - try again
5) Completely unplug power from Roku for 10-15 minutes - try again
6) Factory reset (Settings/System/Advanced system settings) <--- last resort
