Hi,

I’ve had a Hik NVR with 3 IP cameras for nearly 2 years, generally it’s really good. I’ve got events setup on all 3, they tend to work fine for 4-6 months then re-draw themselves IMG_4263.jpeg
This happened today so I tried to redraw them but the system froze. When I restarted it there was an upgrade, which I did, this is the current status

Now when I try to draw an event area it lets me draw it, but when I click ‘apply’ I get this error

Any suggestions on how to fix it please?
