DEVICE unknown user licence error


I installed device evaluation and it worked fine for two weeks then I started getting this error when I try to run my simulations.

"C:\Program Files\Microsoft MPI\Bin\mpiexec.exe" -n 1 “C:\Program Files\Lumerical\DEVICE\bin\device-engine-msmpi.exe” "C:/Users/Ahmed/Desktop/PD_25um_transient.ldev"

Ahmed-PC(process 0): Error: Unknown user

Would you like to reconfigure your license settings?, Response: No
Ahmed-PC(process 0): License error: Unknown user

Hello @ahmedes,

Thank you for your post. That’s a rather unusual error. Can you advise what version of DEVICE you have installed, and what operating system you are running? We may require your assistance in obtaining additional information, but these items may be helpful for us to start investigating. In the meantime, perhaps we can try re-downloading the latest version and see if re-installing the application may get you back up and running again. We look forward to your feedback. Thanks in advance.
