The error suggests something is messed up with your installation. You can using a compatible version of Eclipse and MyEclipse but this is mostly an installation issue. Before asking you to try a fresh install, I would like you to switch to a new workspace (File > Switch Workspace > Temp) and try reproducing this issue.

Let me know if the problem persists.
