Help needed with running a software program on Windows 8.1

I updated my windows 8 to the newly launched 8.1 just today. I used to run a software named "Diet Odin" on my laptop but now it just doesnt start. Well, I would understand if it gave me some sort of error or compatibility issue, but it doesnt. The thing is, I start the software by double clicking it and nothing happens. I tried the troubleshoot compatibility and clicked on test program and nothing happened.

What can be the problem here? Please help. I need to run this software badly, its really important for my business.

Per this image below, it appears that you have to install it in the compatibility mode. I'm not sure what you meant by "troubleshooting compatibility mode" but since this was originally designed for XP, and most of us are not hard-core traders, I would strongly suggest you contact their software support group because I see lots of patches and no explanations for how and/or why they are needed.
