Vietnam 1965-75

I’m using Vassal 3.1.4 and using ?v4 of vietnam module
I can’t play both sides
If I go Free World then Retire and choose NLF it doesn’t let me access NLF counters etc and vice versa
Do I have to save the game and reload it and choose a different side?
or does that still cause the same problem?

Try starting a new game and when it asks for a username and password, hit cancel. The main interface will still appear and you can start a game. Since you no longer have a user name and password attached to a side, you should be able to play both sides.

I’m just guessing here. I haven’t played the Vietnam module but your problem sounds like a username and password issue.
