The error message you are receiving may be due to one of the following:
1. You have not filled out the site specific information in your inventory item. To fill out the site-specific information, please click the title of the inventory item, scroll to the bottom of the page, and click the "setup" link(s) located next to the venue names. Fill out all information and save.
2. If you have filled out the site-specific information, you might be receiving this error on the launch page because you have not yet selected a venue. To select the venue, click the down arrow key under the "Sites" column to the far right of the page.
Let me know if this does not help to solve the problem.
