Server not found

Since few days impossible for my laptop to connect online to the VASSAL (or VASL) server. No message error is displayed.

In place of it I see just the following information with VASSAL:
Main Room (in french Salon Principal) (1)
my user account

In place of it I see just the following information with VASL:

I am used ZoneAlarm as Firewall (already tried to diseable it)
Java 1.5.0.14 &1.6.0.20 are installed on my pc.

My OS is Windows XP sp2.

Is it possible to active a log (like log4j) to have more information about the problem?
