Happened to me today as well, something failing with the update check (possible bad/no response from update site?).
In case it helps anyone, you can work around it by opening mRemoteNG.settings and disabling it:
<setting name="CheckForUpdatesOnStartup">False</setting>

Yep - I get the same thing today too. I'm guessing a) something's offline, and/or b) the handling of this isn't as eloquent as it could be...

It seems to be an issue related to the website currently under maintenance, checking I see traffic going to the mremoteng.org dns and then milliseconds after starting to receive response data the program crashes.

Probably, as @crayfishuk indicates, there is not good exception handling in case the site is down.

Disable automatic updates temporarily fixes this issue.

Linking this to #2541...

We need to move domain to new hoster, its takes up to 24h, selected festive time for minimize impact, but wasn't expected it will hit what way :) sorry for such, at morning I believe it will be normalized.
