Simple Project ToDo Isn't There

You encounter an error message such as "%%os%% Can't Open TODO Files" when trying to open your TODO. Generally, this is experienced in %%os%% because Simple Project ToDo isn't installed on your PC. Because your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking.


Tip: When you have another program installed that you know will open your TODO, you can select it from the other programs listed (see "Show Apps").
