ORBIT not working with Windows 7

Hi there, my operating system is Windows 7 and I was having this Orbit downloader for quite a while already. Now when I opened it, an error message appeared: ORBIT DOWNLOADER HAS STOPPED WORKING and it keeps showing up whenever the program is started. I get the same error message when I use GOM and Grab++. What is this problem related to? I have no idea how to fix them I need some suggestions.
