Steve: 

I hope the problem was that simple but I would be very surprised  if the
moisture caused by the
blowing out would cause your problem unless the reg froze almost instantly.
In the old days, believe it or not, the Dacor factory tech. use to recommend 
flushing fresh water right into the filter to  rinse the reg when it came
out of the salt water or pool. Usually after a couple of good purges or one
or two 
minutes of breathing the insides would be totally dry. This pratice stopped
when pressure gauges came into use but the water involved was a lot more
than the drops involved in taking off the regulator. A simple test for high
dew point
is to do a very quick drain of your bottle an then pull the valve. The cooling 
by the rapid presssure drop will cause condensation and moisture droplets on
the inside of your tank but any puddling or valve freezing is a definite
sign of too
much moisture in the air.

I don't know if it is still done, but when Americans signed in at the park
in Tobermory it used to be recommended that they slow drain their tanks and
have them filled locally because of the cold water temperatures. In Ontario
air stations are tested for dew point anually. I don't know where you are
from but that may not be your case locally.
