MyEclipse 4.0.1 and Eclipse 3.0.1

MyEclipse 4.0 requires Eclipse 3.1 as a minimum supported release due to changes in the Eclipse APIs between 3.0 and 3.1. Unfortunately, a full reinstallation is required when upgrading from the
earlier builds due to changes in some of the low-level libraries we ship
that wouldn’t be picked up properly by an upgrade. If you’re interested,
the details on why this is the case is here:
http://www.myeclipseide.com/PNphpBB2+file-viewtopic-t-8781-sid-4217919be97aebd2b4f0dd8bad8e448a.html

We recommend that you install a freshly downloaded version of Eclipse 3.1.1
and then install MyEclipse 4.0.3 such that it points to the new Eclipse
installation. Once that’s done you’ll be able to open your current
workspace and continue development. After you verify that everything is OK,
you can then delete the current install that you’ll no longer be
using.
