What browser and type of computer are you running?
If you haven't already, I would recommend trying the following steps:
1. Close the Connection Manager and EcoSmart Live
2. Open and log into EcoSmart Live
3. Create a new profile by going to Settings > New Profile
4. Disconnect USB
5. Power cycle your lights
6. Plug in your Radion via USB when the lights are powered and illuminated
7. Open the Connection Manager
8. Factory reset each of your lights by going to USB Device > Factory Reset. This step is important.
9. Use the Aquarium Setup to import and program your lights
If this still doesn't work, try to find each light individually, with only one powered at a time.
