You can check your download credits in your Workspace Settings.
Every time you are downloading rows of data in the Studio, a pop-up message will notify you about the credits used and how many credits your account has left.
What's a download credit?
Downloading one line item (row) in the Studio will use up one download credit.
A line item (row) can be information on an Organization, Deal, Signal or Person.

You can contact your account manager if you've exhausted your download credits.
