I see that your account is showing as Pro (you have a subscription) and you have logged in as a Pro subscriber since posting this. If you are still having issues rendering your scribe as a MOV file, make sure you refer to the instructions in the article Render and share scribes to make sure you are doing it correctly. If you are following the correct procedure, please let me know what happens when you try to render your scribe as a MOV file. If any messages are displayed, what do they say?
how to use the purchased version?
You just login with the account information that you used to purchase the subscription, and continue using it.
If you were already logged into videoscribe when you purchased the membership. Log out and log back in.
