I am getting below error message when going to save my test plan.
I added regular expression extractor and the listeners Error image. I am not allowing to save my test plan now.

Looking into yellow exclamation sign at top right corner of JMeter GUI you have few more errors, if you click on that triangle - JMeter log file will open, most probably it will contain enough information to get to the bottom of the issue. JMeter also writes its log into a file, by default it's jmeter.log and it lives in "bin" folder of your JMeter installation. You can also increase log verbosity to get more information regarding what JMeter is doing.
If you will not able to figure out the root cause yourself - update your question with the log file contents.
You can also try saving your script into a location which does not contain spaces or non-ASCII characters
