Sorry for my medium level english.
firts one...do you have backup of your program? This is very essential, of course.
Have you tried to connect with Control Builder to examine the error log?
Can you go online with Control Builder?
If you have the backup copy of program and you have access to the cpu with Control Builder, you can try to reset the cpu and download again the program.
Hope this help you
