Because of Specctra's Unix heritage, it doesn't like spaces in folder or file names. Looking at the errors you are getting, I believe they are generated because your file paths have spaces in them (notice that each error line breaks at a space). Try moving your files to folders that have simple names with underscores instead of spaces if you have more than one word folder names.
When working with Cadence software, you have better results if avoid special punctuation or spaces in your file names and folder names.
