I formatted my hard drive (wiped it clean) and reinstalled the operating system on my iMac that I had previously registered with a year subscription to parallels access. When I installed the parallels access Mac app (second time after re-installing OS X) and signed in, it treated my Mac as a new computer and gave me a 15 day trial instead of restoring my year subscription. How can I get my subscription back? I paid $50 for it! This is the same computer! Not paying again!
