Just to make sure your download is not damaged, what is the downloaded file size? It should be 18,493,440 bytes.
I have tried downloading it several times now and it is always 18,063KB
I'll try to download it a again next week
That sounds about right; however, you should check the exact size in bytes (under Properties).
I downloaded the file from the US server instead of the Australia server and this file works okay.
Not very impressed but at least this file isn't corrupt.
