Please help I cant save hash and resign anything

I keep getting this popup everytime i try to save hash and resign anything
Well this is what it says

An error has occured while writing back to the loaded Package!
If you see a developer, the following message will help him resolve the issue:

The Process cannot access the file ‘J:\Content\E0000387525CEC\415608FC\savegame.svg’ because it is being used by another process.

Someone please help me figure this out

Ctrl+Alt+Dlt, Click on task manager and look for where the save is being used, then cancel that process.
