I created solar-water-pump-cotroller project last year for a solar heating system for an inflatable hot-tub. It was written using IDE 0.36.1 and all works well, but I now need to make some amendments and change some variables. When I try to create a simulation using 0.36.1 and a version of my project which enables this to be done easily, I get the error message in the title of this post. See attached screenshot for complete message.
The project was created entirely using standard nodes, i.e. no external libraries, so I am baffled as to why this is happening as both my simulation version and the final loaded version worked without any such errors.
I have downloaded IDE 0.38.0 and tried again but get the same error message.
Any help would be greatly appreciated.
