Cannot update through App Store

[Yakibomb]

I'm not sure if this has been posted before, but its really starting to frustrate me.

I cannot update any of my apps using the App Store, it either says "An error has occurred" after attempting to update for a while, or the 'Update' button disappears after i've pressed it. I tired enabling automatic downloads and update and left my computer connected over night but that didn't work either.

Any ideas how to fix this?
