Should I be worried?

[5134516483]

Hi, today i retrieved this mail from you guys

"Dear 5134516483,

Someone has tried to log into your account on Project64 Forums with an incorrect password at least 5 times. This person has been prevented from attempting to login to your account for the next 15 minutes.

The person trying to log into your account had the following IP address: ***.***.***.***

All the best,
Project64 Forums"

I checked that IP and it was a russian IP, but I am German. I changed my password but I am still wondering if I should be worried about this.
