I have a TD-W8960N ADSL Router/Modem. It has been sitting in the box for years. I've been renting a Comtrend modem from my ISP, Execulink, since last September but I want to start using my TP-Link unit. However, I'm being stopped dead in my tracks as soon as I access its interface. I'm getting this weird message and I don't know what it means...

I suspect it's asking me to update the firmware but I don't know that for sure. I've chatted with two of TP-Link's reps and neither one of them was at all helpful. I sent this image to both of them and I don't think either one of them had ANY idea what this is. Long story short - neither one of them could help me figure this out. I'm dead in the water until/unless I can get someone from TP-Link to CALL me and help me figure this out... unless someone on here knows what this message is and how I can make it go away. The chat reps have absolutely no idea what they're doing; they're useless. Why do so many tech companies have such crappy support?
