What URLs did you load into the buttons? Did you get them from NevoStudio Pro (like how they have the pre-built ones in the "S70" section of the Key Groups tab)? I know that Nevo has given out some URLs in the dealer section of the website, but the easiest (and best way to avoid any mistakes) is just to use the pre-built ones right out of NevoStudio Pro.

How many URLs have you tried?

Have you tried running the emulator on your computer when you are on the same network? Do the web sites pop up on the emulator?

They work fine for me and have been for a LONG time now.
