Reported by Jose Manuel Campelo:
As you told me in your last e-mail, I have tested the piece of Verilog-A including your comments, and it was built without any problem.
After building the module, I have created a symbol for it. I have exported an image in .PNG format, and finally I was able to load the module with no problem.
After that in the components menu, it appears a new tab that contains the module that I have built.
Here comes the problem. When I want to choose the symbol for including it in a schematic, an error messages is shown in a window, saying "File not found". And just after that, the program crashes and closes with no further warnings.
