Data modeler errors on generate ddl script

when I try to generate a ddl script I get the message:
Access violation at address 005151f9 in module 'TDM.exe'
I just installed and try to generate it and get the message.
I'm using the 5.4 version of Toad data Modeler

I moved your message to the Toad Data Modeler forum.

Hi Hernan,

what version of Windows do you have? If you have Windows 10 version 1809, please update to TDM 6.5.5 because previous TDM versions does not work properly on Windows 10 version 1809 (see the issue 4868 in the Release notes).
You can find the latest version of TDM here
