Thank you for your replies. I am on Windows 8 64 bit.
On Vista, I thought I was administrator, till I found Administrator account that was not active- I had to enable it and then it was showing up on log in screen. This is what I am trying to find on Windows 8, if it still there. But I do not see anything under accounts.
Another issue: I can not activate Dimension Pro with registration code that came with X2. I thought I registered it before, but may be I forgot. With Dimension it is not grayed out, but when I enter registration code, it says, it is invalid. Yes, I did get new activation code with Sonar X3, but I like my old one to work, as I paid for it! Any thoughts?
