Dear Dreida, I think it would be worth contacting the seller, and he should, based on consumer protection laws, either replace the disc or provide a network key, although he probably won't have the key. At the same time, you can also inquire whether he is selling counterfeit products. Because in any box, if it's a licensed copy, there should be a network key. In case of his (the seller's) refusal, you can safely contact the police and file a complaint. However, there is one seemingly small caveat - you need to have a receipt; otherwise, I cannot guarantee anything, as it is difficult, and sometimes impossible, to prove that you bought the product there. This is in anticipation of your question about whether the police will deal with it. I answer as an expert - they are obliged to accept your statement and conduct an investigation within three days. If you have any more questions on this topic, feel free to ask:smile29:.
Sincerely, White Wolf.
