I can't see ad notifications in the toolbar or the toolbar has disappeared, what happened?
If the toolbar is disappearing or you are experiencing issues with it then you should disable and re-enable it.
If you are using Internet Explorer 8 or above, what you can try is to move your mouse up to where the tabs are, go just to the right and right click. A menu will appear. Make sure that ClixSense Toolbar and Conduit Engine are selected. If they are not selected just click to enable them. If they are selected, uncheck them and then close all your browser windows, reopen your browser and enable them again.
If you are using Firefox, open your browser, goto tools addons. Make sure that ClixSense toolbar and Conduit Engine are enabled. If they are enabled, click disable, close Firefox and then restart it. Go back to tools, Addons and re-enable them.
