Well even though I'm not an apple users it seems obvious, if you have 2 files downloading at once the OS is forced to make 2 names since the one file is in use and locked and it can't use that name then, whereas if it's sequential the filehandle has been released and it can be overwritten.

Well this problem didn't happen for me. It shouldn't happen for anyone else either. You seem the smaller file downloads FIRST because, well, it's smaller. You get that one first and then the HD file. Both files downloaded and worked for me. I've only tried the free files Apple was giving away so far.

"Some users are reporting that allowing 'simultaneous downloads' through Itunes fixes the problem."
how exactly is that considered a fix?
maybe in bizzaro

APPLE there commercial punch line should be

We Make Innovation Move Forward, Because We Like To Stuff Up Our Own Software So You Don't Have To!

Now if some well-intending hacker would just delete Apple Itunes. And while at it, Apple and Stevie Joblobies as well.

Save the Universe! Boycott Apple! (grins)

Oh, and Microsoft too! Let's not forget our favorite bad boy.

If Apple -like the good communist they are- doesn't shut down the forum and apply full censorship as they love to do when users find any "problem" with their products then I'll be quite amazed.
