Hi,
What do you mean with loaded the showfile again?
I'm afraid that if you don't have a backup file, you will have to reprogram the show...
Is it possible you created a new show but forgot to press the save button? When you want to save a show, you will first create an empty showfile on the tablet. Then you can save the show that is currently in the LPU to the showfile you just created.
If there's anything else I can help you with, just let me know.
Greetings,
Bootsy
