Modding Help Game Start Failed

Hi! I've been playing Stardew valley for a while now. I love the game, and wanted to make it more likeable by adding mods to it, but everytime I use SMAPI or Stardew Valley Mod Manager, I get the following error from SMAPI:

SDVMM Version is 1.6d
SMAPI is Version 0.39.5
I am running the 1.04 GOG version of Stardew Valley until I get paid so I can actually support the creators and buy it on Steam.

 

oops, I thought I hit stardew valley, not starbound

 

Since you aren't running the current legal version, are you sure all your mods etc are for the 1.04 release? Using updated mods but an outdated game will cause crashes.
