stacey11,
Sorry that you are seeing this issue.
1) Can you please clarify what exactly have you done before MyEclipse crash ? Did you install any third party plugins to MyEclipse ?
2) Can you check if the debug controls appear and work after opening MyEclipse in new Window (Window > New Window) ?
3) Can you try switching to a new workspace and check if you can replicate the issue in the new workspace ?
4) If you are still seeing issues in the new workspace, can you please attach the .log file located at <workspace dir>/.metadata/.log file.
