Error on update

Hi Guys,
Getting an error anytime I try to update, seems to download alot of files and fail after a few minutes, any ideas?:

An error occurred while collecting items to be installed
session context was:(profile=KNIMEProfile, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).
Unable to read repository at
Read timed out

This looks like a problem with your internet connection.
