Upgrade from 10.18f to 10.18i WD could not find com port on WS2310. Went 10.18f all is fine.
are you using a gps, i.e do you have that setup? (and check you dont hav ticked, use the data for weather display data if you do (as i am now working on capturing the data myself)
also, i had a bug in the com port setup, after i added ability to get a data feed from a environ station via the internet (TCP feed)
and that might have caused a problem
so,try a new 10.18j in about 1 hour from now
