Rating reseted

I changed my computer and my rating reseted. It is even with the interrogation mark. In my profile, I can see the chart with 2 lines. My old rating evolution in green and my new reseted one in blue. Am I missing something (beyond my rating points)?

I am logged in. I can see my game history , and, as I said, I can even see my old rating progress in the chart along with the new one. And to comment here I need to be logged also.

Hello guys .
Can somebody tell why that happened.
My puzzle rating has a question mark now.
I dont know how that happened.
Please anyone tell

@Parth0512 This means that your rating deviation for that rating has risen about 110.

Rating deviation increases over time the less you play in particular time controls. Just play a few games and it will drop back down.

Thanks you very much

You are right. The new computer does not have the cookies that make a 10 minutes game default. I was playing 5 minutes games without noticing. Thanks.
