TC9.3: The object invoked has disconnected from its clients.

On TestComplete 9.2 all was working fine. We downloaded and installed TestExecute 9.3 on another workstation but our automation test crashed in different places with error "The object invoked has disconnected from its clients". I downloaded and installed TestComplete 9.3 and it gave the same error in our script where we were trying to recieve a child of frame window. In "Inspect" window of TestCompete 9.3 i see that frame has ChildCount = 1, but all properties of MDIClient.Child(0) in "Inspect" window display this error (The object invoked has disconnected from its clients). Please fix this error. This problem might have returned to version TestComplete 9.3 to version TestComplete 9.1 (I saw similar bug-report on version TestComplete 9.1, see link below).



Also I am trying to generate report with instruction by link http://smartbear.com/forums/f81/fp4/t65425/tc9-1-the-object-invoked-has-disconnected-from but both Report Generator crash with error "Failed to generate a report. Unknown Error" when I am trying to save reports in file.
