You only need to use CVS update if you want to update your sources with the changes from the Phex team.

You should not execute the ant task 'makeRelease' (it modifies the version file), also please dont modfiy phex/resources/phex.properties and phex/resources/version.properties.
Modification of the version could lead to the problem you saw and also to other problems in case you like to update the Phex sources to our changes.

It would also be very nice if you would share your changes to the Phex code with us. Maybe they can be usefull to integrate into the main Phex release.
