Hi "theHookie", sorry for late response. I've got a problem with my email account so I don't get alerted amymore when there are new posts in this thread.
There are a few different options to select a new template. The information about which template to use when generating sheets is stored in a "settings file". You can switch to another settings file by going to "11 Manage Settings" (from the main MENU in the TVSG program). There you can "2 Load values from a stored settings file", and you will find that there are a few different settings files available that are adjusted to different templates.
If you don't see a settings file that seems to fit what you want to do... here is what you do:
1) From the main menu, select "11 Manage Settings"
2) Select "3 Create a settings file"
3) Follow the step-by-step procedure, giving a name to the settings file, selecting which templates you want to use, selecting which resolution/size you want to have on the sheets and thumbnails etc etc
Does that help? In step 3 you should find template names that match the images that you can see in the "Example sheets" folder.
