Your Couatl.ERR file is from June 3rd, so it's likely not containing all the latest updates of the last days.
Your Couatl.LOG is from today, but it shows a regular session started at KIAD with no errors.
If you get an error, and you have logging active, send the log before starting a new session, otherwise the one with the error will be overwritten. And, if you have logging active, the Couatl.ERR file is not used anymore, and everything (errors and normal messages) goes to the Couatl.LOG file.
