We have begun getting a license error message when we attempt to run the Lumerical FDTD software (I have attached a screenshot of the message). For context, we have been using two separate licenses - one FDTD license that we purchased a while ago and I have been using without problem for many months now, and the other I believe was a free trial of the FDTD software that another student in our group was using. The free trial recently ended, so we have purchased a second FDTD license. This error seemed to begin happening when the free trial ended (even though I should still be using the original license that we had before), but it may have just been a coincidence. I have been having issues getting my Ansys Lumerical account to work (it keeps failing the screening process) and I have reached out to have it re-screened multiple times without luck so far, so I can't email Lumerical support about this. Any help on all or any of these problems would be greatly appreciated so that we can get back to running our FDTD simulations!
