A few days ago my gv-800 system started not responding. after about 4 hours of running, the time freezes but it looks like the program is still recording although it's not. i can't stop the program from the task manager and the computer won't shut down. i have to turn it off manually and turn it back on. i tried to update the drivers but it says that i'm running the best drivers for this program.
