CFDEM-error

Hello,
Today i installed CFDEM coupling on my desktop and when i tried to run one example case i got this error in one terminal, in the other one it created mesh and one blank document file also popped up. could anyone please tell me the reason behind this error and how to fix it. Thanks in advance.
