When activating , says serial number does not exist

[Janey Jahner 0]

I was getting a 401 error and after reading this form, it said to do a download, which I did.  The error went away, but now it says I am in trial mode.  I tried to enter my serial number, but it says the serial number does not exist.  How do I get my software back??
