Look in the .log file in the workspace .metadata directory for a more detailed message. – Betty

did you find a solution to your problem finally? or did you have to re-install everything? – Jacintha

Having same issue here. See #31678104 – Audry

Answer 1

Seems as your MyEclipse installation is broken. You should reinstall it. In my experience such internal errors cannot be fixed which an acceptable effort.

Answer 2

Before reinstalling, try adding

-clean

to the top of your myeclipse.ini file (it's in the same folder as the myelipse.exe file). Remove it after the next launch, as it slows down startup.
