Activation limit reached

Hello,

I bought Mass Effect 1 few month ago, installed it and played it, all were fine.

Recently I changed my PC materials, a reinstallation of Windows was needed, so I started all from 0.

Some weeks ago I wanted to reinstall my Mass Effect 1, the installation was fine but when I want to start, it says that I reached the activation limit, and that I have to contact EA or something like that.

I have contacted EA with the support mail, but NOBODY answered me, I have done 3 request, it says that a answer is able in 24hours, but it's now 3weeks I openened 3 request and nobody answered, so 3weeks I can't use a game I bought.

I hope I can find any help here.

Thanks
