I don't think this KMS will last long.
There has to be a permanent solution for this. As far as I have seen, MS changed the activation process compared to W7. My best bet it to wait a while for someone to come up with a reliable solution.
Read the whole thread. But I've no clue about medicine. I guess there are few guys out there with medical background to help you.
Not to worry too much. Let doctors handle the case.
