I found a great tip on a UK template share site here about the problems some of us have with the templates on the US sites. Here is what Caz suggests:
How to correct the date error on US templates…
The easiest solution is to save all the templates that don’t work into a folder called “US Templates” and then when you want to open any of them to cut, go into “Control Panel” on your PC and change “Regional and Language Options” and change to “English (United States)” and then you will be able to open all the US templates. Remember once you have finished viewing/cutting the US templates to go back and change your system to “English (United Kingdom)”.
and it works!!!!!! Thanks Caz.
