Thanks to a comment, I tweaked the data retrieval to ignore SSL cert errors. You can change that tweak back if you go through the pain of updating the SSL libraries on your Windows boxes (it doesn’t seem to be an issue on OS X/Linux).
I also changed the date routines to use
as.POSIXlt instead of
ISOdatetime as the latter seemed to cause issues for some folks.
All changes have been pushed to the github repo.
