I don't think you have reached maximum number of components.
You have, most likely, made an error somewhere (syntax error is most common). If the game tells you line and file where error is located then it is just a typo. If it just tells you the problem file, but no description or line for error, then you have made something the game doesn't accept.
If you don't find what it is, you can post the files here so I can take a look.
