Hi,

I just changed to Kepler and everytime I run an eclipse instance, I get the following error:

Hi Phil,

It appears that you've hit bug #416828 which has been fixed in the latest interim version.

Cheers,

Hi Dimitris,

yep that seems to be the problem. How can I install the latest interm version in eclipse? Have I got to uninstall the stable Epsilon core and then install the Epsilon core from the interim version?

Cheers,
phil

We've just released a new stable release (1.1 SR1) to fix these urgent bugs. You should be able to upgrade with the standard Eclipse facilities, using the stable update site:
