I purchased the full version about 3 months ago, and still have my registration email. I've been having BSOD issues with my brand-f'ing-new computer, and was advised by geekstogo to check for viruses (I'm running Malwarebyes, Avast and Comodo firewall). I wanted to make sure Malware byete was upto day, so I clicked update. Then I got an error that It couldn't overwrite a file that didn't exist (oops, didn't copy the message). Then it promoted me to reboot. THen it wouldn't run at all. So I un installed antimalware, and tried to redownload, but the only options are the free or to pay for another. How the !@$!@#%$! do I download another copy and reuse my reg code I paid money for??? (Sorry for the frustration, but I"m about 3 seconds from throwing my new $1300 computer into the wall...)
