error code: 0x80004002 when updating


I need some help please. I downloaded MSE a few weeks ago and when trying to update I recieved error code: 0x80004002. My date and time is right and I cannot manually download the definitions.

However when I first downloaded it I somehow randomly got it to update after many failed atempts and visiting the MSE website(it just started updating out of nowhere).

That one time was the only time it updated. I removed the program and readded it today but it still won't update. So would anyone know what to do?
