Thanks for the reply. I have already checked this and thats not the problem. The MIME typs is added, thats one of the things I first checked as I have had problems with II6 and other sites. IIS has changed dratically since IIS5. 6 has far fewer MIME types by default than 5 did. Nice of Microsoft!! I have looked on the Macromedia support forum site and everthing they have suggested I have looked into also. Without any luck.
