KT200II Won’t Open After a Break Here’s What Fixed It

ECUHELP KT200II User feedback:
I haven’t used my laptop for 14 days, and now when I try to connect to the KT200II, it won’t open.

I checked the dfb2xx.dll file, but it wasn’t there. Usually, when this happens, I delete that file, restart the program, and it works fine.

I deleted everything and reinstalled it this time, tried different Wi-Fi networks, but still nothing.

When I try to run it offline, it says the license has expired. If I try to update, I get an error—probably because I haven’t connected online for the first time yet.

Is there any other solution I can try? Also, no Windows updates or similar changes were made.

Finally, he solved; he found the time wasn’t set correctly.
