I can only repeat and confirm it doesn't happen here, and in case it does, any one of the solutions in the manual at Page 97 will work. That is, assuming the Couatl engine IS running in the first place. Because if it's not, nothing you read at Page 97 will help you, the relevant page is the general Troubleshooting at Page 95, which discusses cases where the Couatl engine is not even starting.
Also, be absolutely sure you have the latest version, so run the FSDT installer again using the CHECK option and, if you suspect something might not be updated online (because you see the same files being downloaded over and over), try the OFFLINE installer after performing a normal update.
