Trouble with Eclipse while opening rptdesign - eclipse

Question

I'm having some problems when I'm trying to open a rptdesign. The name of the file doesn't load, it stays all blank and when I close the file the Eclipses throw a null pointer exception. I'm using eclipse.buildId=4.4.1 (Luna) and java.version=1.7.0_75. Anyone know how to solve it?
Follow the stack trace:
Message: Problems occurred when invoking code from plug-in: "org.eclipse.e4.ui.workbench.swt"

Try switch to a new workspace should help you. Eclipse has almost no settings that are stored outside your workspace.
if it does not work, I advise you to open your file with a text editor "notpad ++ for example" and see the version of birt used in the development (see tag), download and use it to open your file.
