hi, i am new to this forum. I just saved my publisher file after working on it for 4 hours. But when I want to open it, it doesn't work , it displays an error message.
I need this urgently and i have no time, help!

the message says: "Publisher has detected a problem in the file you are trying to open. If you are certain that this file came from a trusted source and does not contain harmful information, click OK. If you received this file from another person or machine and are not sure that the contents are safe, click Cancel."

what should I do????????????????????
