Messing up moving my software

I am sure this has been covered many times and I apologize for my stupidity but here goes. I bought a new house in November and it took me until now to get my Davis Vantage PRO2 back up on my roof. I bought a new computer and decided to use it for my weather station. I tried to migrate the information from my old computer and I could not get it to work. So I installed the Weather Link logger software and went ahead and installed the old Weather Display I had downloaded when I first installed it and it installed as a trial. Can I get a new registration number without paying for it? I do have the registration number from my old install. Also can I update the old trial software without uninstalling the old version?

First see if this FAQ helps:

If not email your Original registration proof to Brian ([email protected]) or PM him “windy” the information.
