You are more than welcome
Lot of times there are trial versions so you can make sure the plugins and instruments works with your setup before you spend th money so look into that aswell beforehand and you know you can demo PT11 aswell here:

You do need the new ilok2 key in order to demo PT11 and thats a $40-ish purchase so when its time to look into this don't forget that ilok2 key
Its a FULL VERSION and works exacly like the paid version for 30 days so when you are looking into an upgrade make sure you demo PT11 so you know your computer and interface etc works well before you pull the trigger.
All the best
