Can´t download ep 4

I can`t download episode 4. Been trying all day, and after having downloaded about 35-45 %, I get this message:

You must have an internet connection to access this feature.

Problem is, I have an internet connection working just fine.

The problems started at the end of episode 3, where the game would freeze for approximately 30 secs ever second minute or so. Now, I can´t download the next episode - #4...

Extremely annoying. I payed for all the episodes in one from telltales website.

To quote Telltale:

"I know everyone is frustrated with the download issues encountered since Episode 4 launched, but I have some good news. After investigating this issue thoroughly, we have isolated the problem that was preventing everyone from downloading Episode 4.

To correct this, please shut down and re-launch the game application. A new patch will automatically download and then you should be able to download all episodes through the in-game menu. I do apologize for the delay in sorting this out".

This does not seem to be the case for me...

Any ideas or suggestions?

EDIT: I´m on a MacBook Pro. Snow Leopard.

Now, it won´t even start the download. Just the message telling me I need an internet connection. Why can´t I download the game I paid for?
