What, exactly, are you doing?
The phrase "loading project for 2nd time" is somewhat vague.
Screenshots of exactly what you're seeing would help.
Some files are repeated on timeline (project bin has copies of same files with new names)
That's not normal.
That's why i'm asking if anyone knows what could be causing it.
I nearly gave someone a wedding DVD with the speeches repeated.
Luckly I noticed it before burning the disk.
