reactivation not happening

hello everyone! I bought cubase 8 elements a while ago and recently I formatted my computer. now I can’t reactivate my licence although I followed the step by step procedure to do so. I tried several times to contact steinberg so that they could help me, but so far two weeks have passed and I did not get a response from them. can someone please tell me how I can get in touch with a person from steinberg ? thanks !


Why you cannot reactivate? What happens? Any message? What is the last you can see?
