Yeah... the site will start blocking downloads if it gets too many requests for files over a certain period of time. I've managed to get that message myself, but only after I've been doing a *lot* of testing. I had to put it in place as there are eight zillion download sites out there that CONSTANTLY attempt to download the software to keep their sites updated, whether or not there was a PAD file present (the PAD file is an info file for the software available). My site has no bandwidth restrictions, but I put that in place anyway in case I change hosts.
Are you running any type of browser add-on that opens multiple streams to download files? If so, is there any way to add an exclusion for VoiceAttack.com (it's only 3mb or less). I can fix you up, but that will be later this evening.
Sorry about that!
