MS Project Error: Problem on sending the command to the program

Hi folks,
Almost all my work in the office needs MS Project. Our files are stored in the server.
When the day starts, I opened my file for some updates, I meet and error that I pasted below, and it took me minutes to open the file.

There was a problem sending the command to the program.
As I looked into the error, on my understanding there is a problem with the file. So for better analysis and isolation of the problem, I copied the file to my computer. When I try to open the file, there is no problem and I can open it in a normal speed.
I am now asking for some help on what is the cause of this error.
