Design canvas editor not working

Question

I think I may have started the program before the auto-updater finished it's work. After closing it up and restarting it I was no longer able to see the design canvas editor for any of my projects. Thinking I may have screwed something up I re-installed everything, including wiping out the projects I had.
The only other thing that may or may not have influenced this is that I recently installed the Java-Plug-in 1.4.2_05 though after a time or two I removed this as well.
The design canvas editor appears to be dead. I have re-installed several times. Creating new projects results in the same problem. The Project Navigator works and it is aware that the project is open. I have tried both the base install and a fully updated install.
Has anyone else seen this before?

Answer 1

From the stacktrace in your log file it looks like the canvas designer module has been disabled. To undo that, either go and reenable it via the options dialog, or simply nuke your {userdir}/system/Modules/ dire]ctory. (This is assuming you want to continue using the rest of your user directory in case you've done lots of option customizations etc. Otherwise simply nuking the entire userdirectory as Winston suggested works.)
