Ouch, no way that you can use a Linux server, eh? If so, it'd be a lot easier to help ya. XD That's just because I'm more familiar with the commands.
Anyways, there's a few methods available to you. BigDump as described above by jchamber2010 is one I've surprisingly not heard of until now, but seems it's been around since 2003. Still, with a "0.29b" version, I think I'd stick with something a bit more well known. xP
MySQL Dumper (
http://www.mysqldumper.de/en/ ) is what I use when I don't have shell access to servers, but I do have FTP access. (When I have shell access, I just execute the command-line statements to restore a database, but I honestly have no idea how to do that in Windows. I'm sure there's got to be a way, though, and that would probably be your BEST option.)
