Restart validator, or possible your computer

Hi Bob.

NoClassDefFoundError in Java comes when the JVM is not able to find a class at runtime which was available during compile time. But If you look in opencdisc-validator\lib, you should have a file called poi-3.9.jar. As long as you do, then the solution we've seen work for other clients with this error is to close opencdisc validator and try again. Worst case scenario, try restarting your machine and retry the validation.
