Problem with Date format
Some releases of Windows 7, Windows 8 and 10 have incorrect settings of the date format and it causes that TimeMaker (and some other applications) doesn't perform correctly.
Here is how to fix it.
At Windows 7 is the problem easy to fix.
Go to Control Panel, select Area, and language, click on more settings and press the Reset button.

Unfortunately at Windows 8 and 10 is a similar problem, but it's harder to fix.
If you try to change date format through the Control Panel it won't get changed.
You need to do the correction manually.
Start program regedit.exe (via Win+R and type regedit).
Go to HKEY_CURRENT_USER\Control Panel\International
Find ShortDate item and change the value to D.M.yyyy.
Then you need to restart the computer and it will start to work.
