buying serum

just about to buy serum.
i have a few questions.
i cant seem to link my account with my email.
how many downloads do you get? do you own it forever?
i already have the demo

how much dose it cost in uk?

Thanks for the interest in Serum.
You can change your email address in "your account". I don't understand your issue there, you can use the contact form if I can help further with that.
You can download use Serum on multiple computers if you personally own them.
you own it forever - updates are always free.
The exchange rate varies day to day, I believe it's right around 148 GBP at the moment.

Warm regards,
Steve
