Marscommander

Hey guys, Been playing this game modded for years and started getting some bugs so I reinstalled it today. After patching to 1.9 the mods tab refuses to show up in game browser. I've tried removing and recreating the folder in documents and re-downloading mods. I read somewhere that starting a skirmish match would fix this error, but after starting up a couple skirmish and campaign missions the tab still doesn't appear. Any help with this issue would be appreciated. Thanks
