AS2004.5 for FS9: Download ERROR

Hi,

I freshly installed FS9.

I also have AS2004.5 installed.

First startup worked fine.

Now I get an download error right after the program start. The download status shows 10kb and then stops.

Then it says "download failed, will try again with next update"

My internet connection is perfectly fine, no firewall or anti virus issues. Weather download via FS9 works too.

Any ideas?

Cheers 

Frank
