Activation " Cubase LE"

Hello everyone, two week ago I bought a tape recorder “Zoom H2n” and together with the recorder they sent me a code to activate the “Cubase programs and The Wave The lab” Even though he having followed all the instructions for download through eLicenser control center etc I became account “my steinberg” etc … nancy.
When I go to activate it with the “new activation code (s)” 0240 7CXX … BEWU … VZ00 14D5 // // //// eLicenser center stops and tells me it will be a solution.
I kindly ask if someone can help me understand at least not think it’s a fact of my PC Windows 10 operating system with 4.00GB RAM …
I also asked for help to “support” but no one answered me.
Thanks for the attention.
