Water Physics Plugin Project Compiling error

Hi I was doing some testing with Mans Isaksson Marketplace water physics plugin.

I downloaded a sample project and it ran well, I could edit and compile objects with no issues. After a crash, I received the error below. I deleted the entire project and re-extracted it from the zip file, reinstalled the plugin and nothing worked.

Whenever I compile I receive this error. I can still play test normally and navigate the project with no issues except I can’t compile.
