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

In addition of this ......If you are not able to login with existing program then you can try to download with one blank program (make seperate program) and once program is downloaded then make boot project and wait for 5 sec....after that restart the PLC and download your program...
