Is this the same computer that I am currently working with you?
If so, this topic needs to be closed as I have mentioned already: "Refrain from making any changes to your computer including installing/uninstall programs, deleting files, modifying the registry, and running scanners or tools." Although this topic is not actually making too much changes I would like you to refrain from doing so.
Once we are done, you can Pm a MOD to re-open it if you need to.
And regarding your question, yes, you can save it before your computer shuts down. I can let you know in the other topic once we are done.
Thanks for understanding.
