TMD.exe 5.3 crash when hovering menu items shortly after opening program

Can anyone help me here? After installing Toad Data Modeler 5.3, it will open fine but it then crashes whenever I start browsing and trying to select on e of the menu options at the top. I downloaded v 5.4 beta and that does the same thing. Windows Event Viewer log isn’t much help as below:

Things I have tried thus far:

  • Rebooting Machine
  • Uninstalling and reinstalling program
  • Enabling .net 3.5
  • Different version (5.4 Beta)
    OS: Windows 7 Professional 16GB RAM
