I had purchased Movie Studio Pro 17 Platinum over a year ago and am now trying to use the software for some upcoming projects, unaware of the fact a serial number was required to activate it, I had purchased it through Amazon rather than MAGIX's own website and apparently a serial number code was provided in the download via email but that email is long since gone now after checking for it. Is there any way to find the code that doesn't involve purchasing it again? Thank you.
