TaxiMATE appears to be pretty old, so it's quite possible that it isn't compatible with Windows 10. (I couldn't find any compatibility-related information on its website). Try launching the tool in compatibility mode with Windows 7 or older by right-clicking the executable, going to Properties -> Compatibility, checking the box marked Run this program in compatibility mode for and selecting the desired version of the operating system from the drop-down menu. Also, launch the application as administrator.
Alternatively, you can try contacting the developers using this address firstname.lastname@example.org and see if they can help you out with your issue.
