Recently, I've bought Vegas Pro 18 Edit through Humble Bundle. I got a registry key, but I can't register my product. It seems that it cannot connect online to register the product (I tried to install Vegas Pro 14 as well, but had the same issue).
Strangely enough, I tried to use the trial version, in hopes that if I used it, I could register the key somewhere. It asked me for a trial key, which it sent to me on the magix website, and THAT key did go through, but not my keys that I bought?
I also registered the key on the Magix website for products and it DID go through, so it's not like the key is invalid. It simply won't connect to verify my keys AT ALL.

I'm using a Windows 10 computer, and I already restarted my internet connection multiple times, used CCleaner to clear cache and other files, re-installed multiple times, too. The only thing left is to reinstall windows but I don't think this would merit to reinstall all my programs just for this one.

I still have no idea what to do, and it's very frustrating.
