lower clock to 700 not 850
does anything show at the pool?
do you have any gear working on the pool?
If you have no working geaR AT the pool other than the grid seed it is harder to test.
you could point them to my account on viabtc.com
pool stratum+tcp://ltc.viabtc.com:3333
user philipma1957new.gridseed1
password x
if it connects and mines it is a pool issue
if it does not connect it is something else
just point 1 to my info above.
we can see if it works at viabtc
make sure to set clock to 700 not 850
