It seems you are using Tableau Public instead of Tableau Desktop. Could you check that?
Hi Ramon --
Nope, Tableau Desktop (Personal Edition) Version 8.1.0 (8100.13.1119.2300) 64-bit. Product key is valid and expires june 2014.
Any other suggestions?
The problem is that the user license for Tableau Desktop (Personal Edition) does not includes connectors to databases, just to local data sources (Tableau Data Extract, Microsoft Excel, Microsoft Access and Text) includes also connectors to Windows Azure Marketplace Data Marker and OData.
You need Tableau Desktop Professional.
My suggestion now for you is to download Tableau Desktop Professional and install it, you will have 15 days under a trial license. Other option is to talk to your Tableau Sales Representative to find an alternative.
