Luckily I have PS3 so it's FREE YA :rock:
The cost of live isn't the issue, for two reasons. One, he stated he doesn't have DSL/Cable internet, so even with the free PSN he's boned. Two, even with XBL silver you can download this type of content.
Not flaming you, just clarifying.
As for the OP's predicament...
Maybe you have a friend or relative that can give you internet access to download the file?
