I haven't used SMAPI since last year so I decided to download it for the new beta. Every file is up to date. When I open SMAPI I am met with this: [12:42:49 INFO SMAPI] SMAPI 2.6-beta with Stardew Valley 1.3.9 on Microsoft Windows 7 Professional [12:42:49 DEBUG SMAPI] Mods go here: E:\SteamLibrary\steamapps\common\Stardew Valley\Mods [12:42:49 TRACE SMAPI] Log started at 2018-05-05T11:42:49 UTC [12:42:49 TRACE SMAPI] Starting game...

Press any key to exit. Any advice?
https://stardewvalleywiki.com/Modding:Player_Guide/Troubleshooting#Fix_common_error_messages Could be relevant. (Also, SMAPI is currently on beta 5, you should update.)
I've just fixed this problem for myself. I ran across this thread https://github.com/Pathoschild/SMAPI/issues/430 I uninstalled VoiceMeeter and it fixed the problem like the poster in the thread. Hope this helps.
