Issue with downloading knime extensions

Hi,

I am trying to update my knime with extensions to enable extra nodes like remove duplicates. But i am constantly running into the following error. Did anyone experienced the same? Any resolution 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=).
Problems downloading artifact: osgi.bundle,com.vernalis.knime.source,1.5.0.201511111056.

It looks like you have an unstable internet connection and the downloaded files are corrupted after they have been downloaded. You can try to download the a zipped update site and install from there.
