So... Do you still play the game?
Anyway, assuming you are in Windows, did you check the Recycling Bin? Unless you changed your system settings, all deleted files are stored there
until you delete them again, undelete them, or the operating system needs the space and deletes them.
1) Open the Recycling Bin
2) Look around for your needed file
3) Select it and choose undelete. The file should be restored to where it was deleted
