Hello, Mr. Allen

I have submitted the final assignment but the result is “0” score. 
I wonder whether you are still marking or you cannot open the file.
Since my computer had suddenly shut down, I submitted the file by using my spouse‘s office computer. 
And I am worried it might have been secured so that you couldn’t open it.
In case you cannot open the file, I attach the file here. 
I hope that you understand my shoes and get a good result.
* I have tried several times to upload previously submitted final assignment here, I failed. Please, let me know how to handle.

Thank you.
