This is a red flag that something has changed in your install. Did you try and install WTP or another plugin? I would suggest a brand new clean install of Eclipse 3.1.1 and MyEclipse 4.0.3 (just released today) into a new location, then open up your existing workspace to work around this issue. This will be the fastest way as opposed to trying to troubleshoot which plugin is causing the trouble (most likely WTP).
