Flash 8 or 9 Publishing error after Flash9 installation

Question

Hi.
I had my dear Flash 8 installed and everything was working
fine till I decided to install the Adobe Lab's Flash 9 AS3 Preview
Alpha.
Since then, inside Flash, every time I publish a movie and do
"ctrl+Enter" 2 times to simulate download, it gives me some kind of
error, not showing the contents and stopping the movie without any
kind of warning.
I already uninstalled the Flash and the Flash Players,
reinstalled everything and still nothing.
Can anybody hel me with this problem? I had some urgency on
solving this.

Answer 1

Already uninstalled everything, flash, players 8 and 9, even
a trial of flex.
Still the same problem.
I have 3 scenes:
- scene 1 - preloader based on a simple mask moving over text
(on percentage = 100% jumps to the next scene);
- scene 2 - a logo and a simple animation with some blur
filters;
- scene 3 - the homepage.
The very problem is when I test the movie and click 2 times
"Ctrl+Enter" to simulate download. When I do this, the movie stops
at the beggining of scene 2 showing just the logo and nothing else
for a long time (really long time) till it starts play again to the
next and final scene.
Anybody familiar with this problem?
