Hey Zena
I know you posted this a good while ago now and have probably either given up, figured it out or upgraded to pro 10 but i figured I’d post this (as a first time poster) as I had a very similar problem this morning and couldn’t find the answer out there.
It seems that the trial has the most up to date update and if you (re)install pro 9 you simply get 9.0 and not 9.0e. All you need to then is this
– Open Vegas
– Click Help -> Sony on the web -> Latest updates
– Select the most relevant update for you and download and run
NB – you will need to re enter serial no etc
Hope this helps someone out there
