I have asked the above trouble for me. Some people answered me. Then I have used their hints but still without success. Please help me because I already have lost more tham 20 hours and ... nothing new.

My computer is running under Windows 7 Ultimate operating system. The processor itself is named T9400 (so called 64-bits).

Movie Maker was installed and unintalled several times during last week from official Microsoft page (together with Microsoft Security Essentials of course).

The result is still the same ("sound of black screen") and my knowledge is finished.

Kindest Regards.
