How do i update serum without install a new .dll to the presets folder of FL Studio

I bought serum a year ago and I am having trouble with the "this preset was made with a newer version". Please help?

Hi,

Most likely you purchased under another email address. I would suggest to use the contact form, and provide any other email addresses you may have used which I'd be happy to look up for you, or a date or purchase confirmation email if possible.
