when I open ninja today, it says an update is available, two buttons , install update, or close ninja. So I have to choose install update, then in the middle of updating , there is an error message: could not open key : unkown\components\...

I knew that the software update for ninjia1 stop some time ago, so how come there is an update now, and then there is a problem with the update?

what should I do? I assume that while there is no more update for ninja 1, it should still continue to work. Isn't that correct??
