Thanks so much for your suggestion. Apologies that it has taken so long for me to swing back. I couldn't find a way to respond to you directly.
I have tried your suggestion. I did not have a ~p2.repository directory. I did have a cache directory under the ~p2.core directory which I deleted, but still with no good result.
The error message says that it can not read the content.xml repository file. Could this be an issue with the correct JDK or Java Runtime? I have also tried to do the updates and receive similar responses. Could it be that these repositories simply don't exist any more? I have visited the website with a browser, but that doesn't let me in. The URL exists, but gives the message that this is normally accessed via the Eclipse tool.
Any other suggestions would be appreciated. Te recap, this is Eclipse Kepler 4.3.1 for BIRT report development.
