All it shows is “An error has occurred”
log file shows the following. Have downloaded latest version and done a repair, no difference.

Neily,

Sorry that you are seeing this issue. Thank you for sharing the stacktrace.
Can you please start the Angular IDE with -clean command line args, switch to a new workspace and see if it helps?

Here is the FAQ to start MyEclipse using -clean command line args : https://www.genuitec.com/forums/topic/troubleshoot-using-the-clean-command-line-argument/
Follow the same steps for Angular IDE and switch to a fresh new workspace.

If the above suggestion does not work, then please reinstall Angular IDE instead of a repair. Delete the .deliverycenter.installs file located in your user home directory, rerun the downloaded AngularIDE installer file to install a fresh copy to a different location.

Apologies for inconvenience caused. Please let us know how you get on with this issue.
–Swapna
