I am having problems with my program and need help, I went into the hospital on th 13th for spinal fusion surgery and before I left I turned my computer off, when I came home yesterday I turned it on and it did an auto windows update, I am using win7 pro, today I went to go onto chief and I had to register Chief again which I couldn't understand but I did and when I got chief back it started updating my lib. don't know why, then when I went to open a file that I had just printed the day before I left my plan screen was all different and I lost all my icons, the I restarted my computer to see if that would help and it ask for me to register again, so I did a system restore with no results, and when I open chief again it opened but with no favorable results, and I get this message in chief
