Archos 101 G9 touch screen quit responding

I've had this G9 for about 2 years.
Slowly the screen has become unresponsive.
First you could turn the screen off with power button and back on and it would work.
Then it got to the point that you had to hold the power button for 10 seconds to reboot it.
Now nothing works.

Is this fixable? If so, how?
I'm a mechanical engineer so try to keep this in laymen's terms if possible.
Thanks in advance!

Foxfi quit working

Help!! Foxfi stopped working this evening on my Verizon Note 4 and my wife's S4. I am located in central Sussex County, Delaware. We are both on unlimited plans but with different accounts. 4 G signal is strong (-88db). I activate WiFi hotspot from PDA Net. It takes me to "settings", I toggle Mobile Hotspot from "off" to "on". It tells me that it is checking subscription status and after about 30 seconds I get the Error message that this service requires a subscription. I use quite a bit of data but my wife (on a different account) uses almost none. Anyone else having trouble all of a sudden? Any idea what may be going on? Help!! Thanks.
