Error when loading composite project on soapui pro 3.0.1

Hi, we just got a deployment and we can not load our composite project now. I probably suspect because some of our datagen that pulling value from the database(using groovy script) now messed up because of the DB changes from the deployment, and caused this problem.
But again, we can not even open the composite project. Does soapUI load the datagen when we opening the project?

Bellow is the error that I found in error log. around 5 of these same errors. Please let me know if you need more information.
Thanks,
Ferdinand
