Startup manager Freeze

[coachhagen]

so im fairly new to the modded simcity world, and was looking for a solid way to manage my plugins so i didnt have to have every one for every region. i stumbled across the startup manager. however once i click on a region to start the game, the file manager freezes and is not responding on the screen that reads "starting up, Initializing sumjserver". im on windows 10, clean install. any help would be much appreciated
