pro tools 11.3.1

[vomvix]

i do have the pro tools 11 trial version for 30 days
i try to update them to 11.3.1 but in my account i don't find this product
it seems like for using pro tools 11 with my yosemite based mac 11.3.1 is better
do you know any other way to get it ?

visiting and sign in to my account in avid
then go to my products and registrations i didn't find any products there
is it because its only 4 days that i use protools 11 or because a free trial version isn't a product ?

please help
