Running CMAQ v.5.3.2 error

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?


Thank you!
