I had quite major hardware failure recently. Asus rampage V extreme fried itself, 5960 cpu and one of memory sticks. Bummer really. Luckily hardware issues are now sorted, most of it under warranty, with net result of me having new motherboard, Asus rampage V extreme 3.1, cpu (same) and memory (upgraded from 2800 to 3000). All starts and to my surprise motherboard also detected RAID0 and kept data intact. Now windows 8.1 threw its toys out. My key appeared to be blocked and windows requires activation from now on. Microsoft online customer service person told me that my key is "pirated", they can't or won't unblock it (i didn't understand which) and www.mrhightech.com is a bunch of crooks. They suggested to direct me to purchase a new key. For sake of providing context to my frustration, this would be the second windows 8.1 key that stopped working on me. The first one i bought from one of amazon.com sellers, which had been out of business by the time key stopped working. Microsoft had exactly same stance: i bought pirated key, it is my fault and i have to new key from "reputable" seller. I believed them then as seller no longer existed. This time reseller is alive and kicking and is UK registered company, so pirating theme is a lot less likely. I emailed mrhightech.com and awaiting response. What would you suggest I do in this situation? I have no inclination of paying for third key for the same OS in space of 12 months.
