Ran into similar problem when my systemsettings.xml file would somehow get erased. Go to C:/Program Files (x86)/Amazing Charts/SystemSettings.xml open up the file should be about 30 lines of data there example:

if it's empty look to see if there is a systemsettingsbackup file that has the info in it. If so rename the backup file as SystemSettings.xml save it(will need administrator rights to do it) and likely will work after you reboot the computer
