Used ATOM for ages but now won't launch after package installed (resolved)

[togfoxy]

Been using Atom for ages. No problem. Just now I installed some time-keeper package and the installation must have went wrong. I rebooted my computer and now everytime I launch atom I get

The editor has crashed. Please report this issue.

I can't get into the package settings to undo whatever has corrupted my ATOM.

Actions so far:
Uninstalled and re-installed 1.60
Uninstalled and re-installed 1.59
Deleted \AppData\Local\atm folder (MS Windows) and re-installed

There is some trace of ATOM left behind that I can't find. I don't know the anatomy of ATOM well enough to find what might be corrupting it. Any clues?

If I can't sort this then I'm forced to change editors and that would make me very grumpy. :(

Thanks

Edit: It seems the ATOM "shell" remains open and I can access the menu but the main screen/window is all white and refuses to display anything, meaning, I can't manipulate ATOM at all.

Resolved it.

The \user.atom folder lists all the packages installed. I deleted the offending package and now atom loads.

Should the uninstaller remove this package folder as well? I assumed the uninstaller would return my system to a clean state. It seems that's not true.
