Success!
It may take about 20 minutes to update the Block Chain files from 2014,
but only this first time.
Thereafter the BitRaam wallet will load quickly, unless you don't use it for months.

To create more BitRaam, in return for keeping the network going
select the Console tab, then type "setgenerate true"
