does anyone have/had this same connection trouble??

STUCK IN QUALY AGAIN... also last saterday same issue
i seem to be the only one having this problem
im getting desperate 4 a solution...

today i joined the server 10 min before the race started (i was a little late..)
i set a time during qualy and still was last with 0 laps registerd. so the problem is not the switching between sessions, but i think some connection issue where im not sending/receiving server data.
(and no it was not a cut-warning lap or so,i really put down a clean lap)
but i never get a message about any connection issues.
also i dont recieve no more chat message's, if i write a chat and press enter its not showing ,so it seems im not connected with the server anymore
but then again i still see all other cars and they can still see me on track.
so qualy ends - i see all cars go to start grid and im still in the pits.
so i exit and i cant re-join the server cause im still listed on the server, when i try to re-join i return back to the server lobby without any error message


i've posted this many time's allready on the assetto's forum but did not get any help yet
VERY FRUSTRATING if u practice some hours
i do a qualy and then cant start time & time again.

i've checked the router settings, set them all to standart,
i have read the connection issues workarounds, and checked router settings with this info
i have norton 360, i re-installed assetto corsa with the 1.3 update to a different directory and the "allow" rules for the firewall where not valid anymore.
just now i have set them to allow again, hope this fix/improve's things.
i dont know what to do else no more....
