So, I've been trying to play Star Wars Galactic Battlegrounds: Expanding Fronts multiplayer for some time now - but every time I try to launch SWGB: EF in the Voobly client the game fails to launch, getting not even 1/8th of the way through the loading before throwing me back to the Voobly multiplayer menu.

The base Star Wars: Galactic Battlegrounds file works fine in Voobly (minus the in game music missing) and I can play Expanding Fronts single player with no problems so I know the program itself isn't an issue.

However, I ran a boot time scan and found this -

File C:\GOG Games\Star Wars - Galactic Battlegrounds\Game\Voobly Mods\SWBGCC\Local Mods\EF Assets\ef_assets.zip.001|>sounds_x2.drs Error 42125 {ZIP archive is corrupted.}

I've tried asking other Voobly users for help with no luck and reinstalling Voobly *HAS NOT* fixed the file problem.

Please advise.

Please ask another player to share a working copy of ef_assets.zip.001 and replace it with the corrupted ZIP archiv -- that should fix the issue.

Did this end up working for you? I'm having the same issue, but use steam for the game.
