where is the update button/link in the website?

I got serum for my DAW (FL Studio 12) and there was a FLP that I got recently, and it says that in order to preview the preset in Serum, I had to update serum at www.xferrecords.com , but I don't see anywhere where I can update Serum. Can someone help or at least show me where it is or what I have to do? thx

I don't see that you have purchased Serum, if you need help locating that purchase please use the contact form.
