Hi! This is the link

But now I found why it happened. After I posted my question here and didn't get an answer, I tried to find what Toshiba has as service firms in my place.
It's Israel. And found just one and only firm. So, I sent them the same question and got an answer, that I had to register not at this address, but
at www.nomatterwhatguarantee.com . You see! But I didn't know about that, when I bought the computer the seller told me the first address. I even have the check from the shop with the printed address. And I had to regiter within one week and failed. Now I'm trying to discuss with them the point that I am not to blame. It's their computer branch shop called "BUG".
