i want to ask how i know how many stations are using my CC now , i want to know if i can install it in other PC but am not sure if i used all the (2 Licence already).
You can install on as many machines as you like. Of all those machines you can have two of them signed in at a time. If you try to sign into another you will be notified you already have two enabled so that you can sign out of one of the others.
Oh OK that's great..
