DESUMA makes use of the 'dot' language and engine, provided by AT&T. Unfortunately, on some machines, the dot engine does not seem to work locally.
This so far has only been encountered on machines running the Linux operating systems, but it may occur in others as well.
If the dot engine is not working on your local machine, when you add states, they will be placed on top of each other, rather than next to each other.
The dot engine for your computer is located at localDotEngine/<OS>/dot.
Unfortunately, if your local engine does not work, you will be unable to export to any image formats. There is no way to fix this.
If you are running a Linux operating system, a possible soultion has been planned out in the Troubleshooting directory installed to the same place you installed DESUMA.
Go to the Troubleshooting directory, and open the README.txt file found there. Follow its instructions and try running DESUMA again. If you find that nothing has changed, try the next solution.
If you are not running Linux, or the above solution did not help, we suggest you remove the dot engine. As mentioned higher in this help file, the dot engine found on your machine can be located at:
<Installation Directory>/localDotEngine/<OS>/dot
By deleting this file, you are telling DESUMA that you do not wish to use the local dot engine. Once DESUMA knows this, it will use the engine provided by AT&T hosted on one of their servers. This should solve any problems with the dot engine you have.
