HI GLAD YOU FIGURED IT OUT BUT BY THE WAY anytime you have computer issues out of the norm usually it will be a corrupted file or files in your system, a total reload or reset can usually fix your problems but not always!
I have found out usually uninstall suspected file or program or even netframe 3.5 being corrupted as mth loader needs the program to run the loader!!!uninstalling said suspected program and reinstalling your program will usually fix your problem. I sell computers and run into these situations all the time!
sincerely hope this helps anyone in the future!
be glad to help anyone with computer issues
happy new year
Alan
p.s. even a corrupted serial usb to 9 pin tiu can cause many issues!
