Yes, I do get the 'More' for all those shows and they run fine.
As I said, these are old shows. Ver7.?.?. No 'More' and just won't run.
It's funny though because I just went back to my very first PTE show,which, believe it or not, was created in August 2006, and it does run.
[edit] In fact I just created a show with version 7.5.10 and it runs, so I'm stuck for explanations.
