by redo, do you mean reinstall them both? and also which trinity version is the newest one? i see four trinity versions to install...is 2.1.38 the newest?
if you did an update, their was probably an error with the compiler like their was with mine. I had to do a fresh install of the zip download. Solved it for me.
Step 1. Do a fresh "Install" of demonbuddy, download the latest version of your choice (Beta or Stable, Both technically Beta atm )
Step 2. Download EZUpdater <--- Click me and follow the instructions on how to properly install EZUpdater
Step 3. Once Demonbuddy is back online, aka updated again and we can login, it will always keep the plugins you want updated (Trinity/Quest Tools/Armory etc...)
