M2Eclipse & Helios - errors

I downloaded the latest Eclipse Helios Java EE package and installed it with success. Now I want to install m2eclipse and I used the update site http://m2eclipse.sonatype.org/sites/m2e (see here: http://m2eclipse.sonatype.org/installing-m2eclipse.html)

An error occurs:

An error occurred while collecting items to be installed session context was:(profile=epp.package.jee, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).

The other way I found here: http://www.sonatype.com/books/m2eclipse-book/reference/install-sect-marketplace.html is to use the new Eclipse Marketplace. I searched for m2eclipse, but there is no install button only "learn more".

What's wrong? How can I install m2eclipse with Helios?

Thank you in advance & Best Regards.

Use http://m2eclipse.sonatype.org/sites/archives/0.10.2.20100623-1649/ instead of: http://m2eclipse.sonatype.org/sites/m2e

I found a solution. I took the latest nightly build bia the update site and it seems to work.
