sandeeprajarao,
Sorry that you are running into this issue.
Can you answer some more questions for me ?
1) Can you share your build id from Help > About MyEclipse Enterprise Workbench > Build Id ? Paste it here.
2) How did you install MyEclipse ? Is it through Pulse / All-In-One installer ? Archived Update site?
3) Did you install any third party plugins ?
4)
jsp / html – no
Is it unresponsive when you double click on the html file?
5) Can you try opening the jsp file with MyEclipse JSP Editor instead of the MyEclipse Visual JSP Editor ? Do you see the same issue?
6) Start the IDE with -clean, switch to a new workspace, create a new project and check if the issue exists. If yes then copy paste the errors of interest logged in the .log file which is located at <workspace dir>/.metadata/.log here for me.
