Drawing scrambled

I had a drawing finished but when i enter it now it it is scrambled and i have not edited anything in any way. It says the error is with the section view. Does anyone know how to solve it. The file will open perfectly on a usb i have it backed up on but will always open scrambled in the server. Even when i copy and paste into the server file it will open scrambled. Any suggestions?
