Hello,
The other day I purchased and downloaded Movie Studio Suite and then started using it today. I have used a different version in the past but due to one of my drives getting damaged, I do not have that one anymore.
I have no problem starting up the program and creating a project or opening a preexisting one from my files. It seems to freeze and crash only when I import a second, third, or fourth video file. (One of the times I was just clicking between the layouts for the "Project" window and it crashed.) I have imported by dragging the files from the file explorer to the program and through the import tab in the program. When I do drag from the file explorer then both the file explorer and the program freeze.
The video format is AVC or AVCHD (Im not super experienced so Im not sure but I did use Media Info to check). Additional info is in my signature.
Edit: I was able to import 20+ files to the program without crashing if I moved all of the files at once, but then when I tried to save the project using "save as", I chose the location and it crashed mid-save. (At 98%!)
