I know that this is for Vegas pro forum but I cannot click on specifically Vegas pro on the subject drop down.

Around two years ago I purchased a humble bundle containing a Vegas pro 15 key. I used it on my laptop and it worked perfectly.
However, now when I try to do it on my new pc, it doesn't go through and gives me the error number -14. The other products like sound forge went through, but this one didn't. And I did deactivate it on my laptop.

I've contacted humble bundle and they told me to contact Magix but I don't know how to do that. So I'm here in the forums asking for help.
