Hmmm. That suggestion Rowboat_Cop just made would have saved me quite some time (I did the integrity-check, checked win-firewall, connection, even restarted the puter a couple of times) before I filed a "ticket" to the Staff.
At last I asked for info in another forum, which I DID know wasn't the 100%-right one - but where I still hoped to get a decent reply. Instead I got a couple of harsh replies. Anyway - next time I know better - including to be carefull to ask for anything...........
