. . . . Could not find a part of the program. Please install the program again . . . .
This suggests to me you are referring to Vegas Pro or Vegas Movie Studio, is this correct?
If so you are in the wrong forum, the Vegas product forum link is at the bottom of this page.
If you are using Video deluxe, formerly called Magix Movie Studio for versions 18 and later, and Movie Edit Pro before that, or Magix Video Pro X
. . . . The program has been working fine up until today . . . .
What changed on the PC between working and not working, eg Windows update, a GPU driver update?
We also need more information to help diagnose the issue(s) you are having:
The specification of your computer system including Windows version and program version, see this topic for what is required and please quote processor and graphics card make/model in full, and also what monitor/screen resolution(s) you are working with if this is a laptop.
I would suggest you put this information in your profile signature so we do not have to keep asking for it.
