If nothing else will work you can try the Registry Editor fix. Be careful when doing this because making modifications in the Windows Registry can mess up other software if something else is modified.
Press the Window menu and start typing Registry and the Registry Editor usually comes up.

Computer\HKEY_CURRENT_USER\SOFTWARE\VB and VBA Program Settings\IDF Editor
And delete the key group shown as "IDF Editor".
Exit the Registry Editor and try starting IDF Editor again.
