Can't see what's happening from your description. My guess is startup.fil is getting corrupted and won't load.
A suggestion, why don't you try a simpler route? All your *.fil are just text files. Use your favorite programmer's editor on them. MAKE SURE WORD WRAP IS OFF. The Camsoft editor is a good choice. I just use notepad when working right at the machine.
On another note, Camsoft is a powerful control software with a ton of features. Because of this, its difficult for first time installers. IMHO, its near impossible to configure your first machine without serious help. I know the maintenance fee is steep, but it is worth it. If you're not willing to do this, I'd suggest you switch to simpler controls like EMC or Mach.
