Hello,  
I am having issues with running CMAQ.  
I am seeing this message.

* * *

\*\* Runscript Detected an Error: CGRID file was not written. \*\*  
\*\* This indicates that CMAQ was interrupted or an issue \*\*  
\*\* exists with writing output. The runscript will now \*\*  
\*\* abort rather than proceeding to subsequent days. \*\*

* * *

I also looked for the log files, but my LOGS folder is empty. Can anybody help please?
