Ok, I just tried posting this as a question and now undersand the 3rd error message. I sure hope this works and it can be posted.
First Question: How the heck do you post a question? I put "Gimp 2.8.10" For Subject?? I had to go to forum topic.
I am having so many issues that I never experiences.
Long story short: I had to reset my computer (Windows 7 premium - see photo)
No, it's not an option to get my old files back. Long story.,
