The last time this happened, it happened randomly a few times, then deleted all of my programs, including archived ones.
Assembly is like that. Try using all this stuff on an emulator first, that way you know if it is good or not. Did you make the program or install it? If you made it, might i suggest using Source Coder 3 on Cemetech? Also, make sure you backup your files, in case of stuff like this.
