Hello, I am running Yosemite and installed the latest lyx dmg file. When I open up lyx I am given the following prompt: The selected document class article(AMS) requires external files that are not available. The document class can still be used, but the document cannot be compiled until the following prerequisites are installed: amsart.cls See section 2.1.2.2 (Class Availability) of the User's Guid for more information.
After the file opens and I press the eyes to make a pdf, I get the message: The directory path to the document cannot contain spaces. I am not a tech guy so although I have read some forums where people had the issue I still need some step by step advice. Can you please HELP?! I need to make pdf's ASAP. Thank you for your time.
