If you have system restore enabled just go into it and pick a date before you removed anything it put it right again.
You in Australia? - Try getting in contact with their support desk and ask how to install the drivers for whatever device they've sold you.
'3' doesn't mean anything, or could mean something totally different, outside of Australia mate.
