Run, checking, and then freezes at first G0 line...

mecmag

Hello,
I have been using the controller normally for over a month and last week it stops to work.
The manual movements (with arrow keys) works normally.
But when i launch the program, it checks, starts, and freezes when sees the first G0 line. (no movement is made while in play auto)

The code is correct because the same file worked already 10 days ago and i did not change it.

Also, all my new generated files are not working anymore....

is there any suggestions? should i reinstall the firmware? (by the way, i do not have it... someone knows where to download it?)
maybe i deleted some important file in the controller?? (actually it is empty)

thanks
