Can not create video

[doitanyway]

I have windows 7. I imported my files and succeeded to create 3 videos. But now when I want to create a new video, which contains of 5 chapters for example - it freezes at 10 or 20%, than finish and when I open the new created file it contains only 2 or 3 chapters.

I tryied all that you suggested - delete Cathe folder, to reinstall workout blender, but the problem is the same.
I have enough free space on the disc. Can you advise me something else I can do.

Thank you in advance.

To be more clear I will explain what I want to do and what I get:

Cardio core circuit - 1 chapter 5:08 min
Intensity - 5 chapter 11:11 min
Intensity - 4 chapter 9:59 min
Lower body blast Leg drills - 2 10:28
Lower body blast - 20 chapter 5:55
STS TB - 53 chapter 8:51
STS TB - 54 chapter 5:00

Total time - appr. 56 min.

As a result I only get:
Cardio core circuit - 1 chapter 5:08 min
Lower body blast - 20 chapter 5:55
STS TB - 54 chapter 5:00

Total time 16 min.
