There could be something corrupted in the script. The solution would be to delete the Registry for MediaShout. To do this, follow this path: Computer\HKEY_CURRENT_USER\Software\MediaComplete\MediaShout 6.
First, right-click on the MediaShout 6 folder and Export it to your Desktop -- call it something like "V6-BU"
Second, right-click on the MediaShout 6 folder and Delete it.
Restart your computer and launch MediaShout. Please let me know if this helps or if you would prefer to have a tech remote in to your computer to handle it. For an appointment for a call, go to www.mediashout.com/schedule.
Have a blessed day!
