The problem I see is that the distribution of v1.1 includes a ddo-ml.ini file, which inside has a statement "firstlaunch=0"
So upon running for the first time, you will not get the window prompts asking for the path to DDO and the server, and the game will not launch because the path setting is not configured.
And so the workaround for me was to close the ddo-ml program (via the system tray) and just rename or delete the ddo-ml.ini file. Upon the next launch, it will assume first time launch, prompt you via window for path to DDO program files, and server name. Then the gui window with your configurations will appear. A new ddo-ml.ini file will be created for you.
Atomic, if I can suggest, maybe removing the ddo-ml.ini file from the 1.1 distribution will eliminate some confusion for those who download in the future.
And thank you very much for this, very fast and handy tool
PS: If you're like me and didn't see it work the first time, I actually tried to launch the tool a few times. So check your system tray for multiple instances of the tool and make sure you close them all before re-starting.
