I've been trying to download a tutorial/demo that I bought, but it always failed partway through.
I emailed the guy who was in 'charge' of that particular tutorial, and he told me to use DownThemAll (Firefox extension).

This time the tutorial got to a 100%, but now it says "File Access Error" under the Est. Time bar.

Is there a way to fix this, or do I have to re-download it again (for the 5th time) and hope for the best?
