An easier way to update dreamgrid...
1.) Copy the entire dreamgrid folder.
2.) Rename the copy to whatever version of dreamgrid is inside it like this as a folder name ---> DreamGrid v. 5.24
3.) Name the other original copy "DreamGrid Production"
4.) Download and unzip the latest dreamgrid into the folder named "DreamGrid Production"
This way if there is ever a problem You can easily delete the current DreamGrid - Production folder, and then rename the last running copy to DreamGrid - Production. This way you will always have a running production environment with several backups of different versions of good grid environments.
Why you ask? Because if a bug bubbles up through the code, you may wish you could just delete the latest beta and just go back to the latest one that was running fine. This technique can save you hours of pain. I suggest you try it.
