Hi David,

According to the log file, the WRF version was 3.8.

ESM - can you try using the latest release of the two-way version that is available from the CMAS Center Download site under the CMAQ v5.3 page. [CMAQ version 5.3 Release (August 2019)](https://forum.cmascenter.org/t/cmaq-version-5-3-release-august-2019/887)  
Please download and try the WRFv4.1.1-CMAQv5.3 Tarball

Thank you,  
Liz
