Do you see the USB symbol and the Android bug in the notificatio bar when connecting the tablet to the computer using the supplied USB cable? If yes, open the notification bar, tap on the USB connect and turn on storage mode. If you don't see it, something is wrong or you have to go to Settings -> Advanced settings an put USB in "device mode". After doing this you should see your tablet like you do when you use a thumb drive.
I don't believe it had a manual. I do see one on their website. It says something about hitting a mount button I've never seen. When I plug it in to my computer, Windows is looking for drivers for "MID".
Mine worked fine in Windows 7. All you do is plug in the tablet and on the tablet itself you have to click turn on USB storage. It maybe in the pull down menu.
That's great you got it working, glad to hear that yuppicide, I saw your other thread but I don't have any advice for you on that, it shouldn't be long before someone with mroe knowledge can reply to your other thread, though if you ran a search of "market on the 7012 without rooting" I am sure a few good resource threads would come up for you.
