[kanchadales]

Hi, have a server with Plesk 7.5.6 and the windows 2003.
The problem is when I try to open any file.swf, he doesn't open.
Example:
http://www.wtv.inf.br/tv/FLVPlayer_Progressive.swf
Or
http://www.wtv.inf.br/tv/tv.html

All and any file.swf in the server doesn't open...

does anybody help me?
