Assets\Procedural Worlds\Frameworks\Setup1\Scripts\PWPackageInfo.cs(7,7): error CS0246: The type or namespace name 'Gaia' could not be found (are you missing a using directive or an assembly reference?)

Hello, I own all the updates and the latest. First time on these forums. Hope you can help me. Hope I am in the right place to post this. 

I deleted all my assets and tried to install them but keep getting this error. It only works if I create a new project. My old project is ruined so I need to start from scratch installing my assets. 

Error:

If you deleted the procedural world assets then you will need to go into the Project Settings under Edit on the toolbar and click on the player section.  Towards the bottom you will find the script compilation symbols and you will need to delete the ones associated with Procedural Worlds or in your case the ones with GAIA in them.
