The software is not available for public downloading. I've searched on the web and on what's supposed to be the official website, but there was nothing available.
Since I can't test the application properly, I can't say exactly what is the problem, but based on the error message you have provided above, it appears that the file you are trying to add is not compatible with the program or it's corrupted.
Add it again or reinstall the software if you still have the installation package.
