Suggest you read through the responses from op; this suggestion(clear DNS cache and release/renew IP) are not relevant to this issue (Intuit activation tracking via PC fingerprinting). 90% of the responders indicated the recommendation did not fix their issue.
Just because good security practices (VHD, encryption, etc) may be foreign to you, doesn't mean they are not widely used. With regard to an apology, if one were due, one would be made.
