Local Install of Appian Process Model not working

I'm getting this error in my tomcat stdOut log when I startup Appian. I'm able to go on the site but when I try to run/debug my process model it always stuck on the start node and won't continue the flow. Not sure what went wrong, It worked fine other times when I did a fresh install of Appian.
