Problem with synchronizing on Vassel

Iam new here, I’ve been trying to play a game in real time, but have had no luck. I follow the instructions to the letter
and when it comes to synchronizing with another player the synchronize option is always grayed out. I am unable to join
a room as an observer,I can not communicate with anyone in any of the rooms. I am using Vassal 3.2. Can someone give
me a clue of what I am doing wrong.
Thanks in advance for your time and effort on this matter.

Could be that they are on a different update of Vassal then you…Or, maybe the game is locked and not allowing outsiders to observe. Just a thought. Always best to have the most up to date Vassal. They are currently on Ver. 3.2.6
