We have some steps for you to take to clear the message you are receiving.
Clearing your cache in Internet Explorer usually takes care of this message, however, this is not working for you, so let's try something else. Here are some additional options:
1. Directly connect your PC to the internet by plugging it into the Ethernet port on your cable or DSL modem.
a. If you no longer get the maintenance message, that indicates the problem is caused by your router.
b. After you try this, return the router to your setup and plug your PC back into the router.
2. If the problem is your router, we suggest you update the firmware on your router. The link takes you to an article that will go through how to do this;
3. If this doesn’t work, try this as the last step:
a. Close all browser windows on your computer. Make sure you have no internet browsers open.
b. Close Smilebox.
c. Click this link: http://update.smilebox.com/maintenance.html
d. You will most likely receive an error message saying that the page cannot be found, but if you get something different, please let us know.

This will clear the message for you.
