Universe Sandbox writes out log files that may help determine the cause of the problem. They are located in this folder on your computer:
My Documents\Universe Sandbox\Logs
There should be two text files. Could you send me these files? You can send them to:
support at universe sandbox dot com
If you can’t find the files then the problem occurs before the folders are created and the files are written. Either way, I’d like to help you solve this problem.
Did it ever work or have you always had this problem?
