I was a little concerned about…
I was a little concerned about purchasing a key outside of M$. A couple of months after purchasing my keys, I had some authentication issues. The customer support and tech support people were very friendly and helpful. I really screwed up my system. They were patient and either directly fixed or painstakingly walked me through everything necessary to bring my systems back on-line. THIS is how I teach my COMPTia students to do Tier 1, 2 tech support. Thank you.
