Can not open/connect "Ninjatrader fatal error"

[polleo]

After I have followed the setup steps for IB, Ninjatrader keeps crashing when I open it giving me this error.

"Fatal error: one of the following jar files is missing from the classpath:
jfreechart-1.0.9.jar
jcommon-1.0.12.jar

Please help. Reinstalled TWS, reinstalled Ninja as well. Nothing.

Hello Polleo,

Thanks for your post.

So I may assist you further please answer the following.

Can you launch Traders Workstation by its self?

What version of NinjaTrader are you using? (Example: 7.0.1000.16)

* You can check under Help -> About

What build of Traders Workstation are you using?

* To verify what version of Traders Workstation you currently have log into Traders Workstation
* Under Help go to About Traders Workstation...
* Scroll down and look for Build

Thanks for quick reply, I am using Build 927.7 of TWS and 7.0.1000.16 Ninja. Yes I can launch TWS by itself. I was using 938.1 and reinstalled to previous version trying to fix it
