Incorrect program

If you want to cut a video, it can happen that is gripped at a Aktiuon (fade in, fade out) on keyframes back that then "," caused in the German system than with decimal separation problems. As far as the effect that none of the projects stored longer can be called. The problem seems unknown, but an improvement on program services I could not find on the Internet. This occurred to me after the first day use, and all work was for nothing, because no file of the element 13 can be opened more. Error message files are corrupted. It is currently mähsam to find a solution that addresses this issue. If not already useless the program after a day !!
