Darwillie,
Actually I am having a similar problem, and have read several others having the same. (I'm also an earthlink user on a cable braodband connection). It's not a download problem as both of us get the download file. Its an install problem.
I am able to download the file, but cannot install as I get an "invalid Win32 application" error message. Tried everything twice. E-mailed support, posted here, and on critical issues forum, but no help yet.
If I get anywhere, I'll let you know. Good luck to us both,
Ken
