Finally, i receive the error message like:

|Developer: Adobe Systems Incorporated||File Size (Bytes): 4503552|
|Software: Adobe After Effects||Operating System: Windows|

And have you actualyl done what it says and reinstalled AE? Other than that you need to provide proper system and version info.
Nevermind, i reinstall the AE.
