unpacking the zips

[dxdavieau]

Thanks guys, I appreciate your time.
I'm baffled by all this extension management stuff.
When I start vassal, I get the list of all the games I have vassal modules for, when i click on panzer grenadier uber 3.2.17, I get a start up screen where i can choose 'start new game offline'. when i pick that it asks me to select boards but the pulldown list is empty. how a/o where do i manage extensions? Sorry, I'm not very computer savy...

I was expecting the zip files to include some sort of module specific .mod, what I see is a bunch of vmdx files
for aircraft, leaders, boards and OBs

" right click on the Uber entry in the Vassal window...." I'm not seeing this...
