Here's what I did to get it working.
1. Download the 1.7.10 minecraft forge install package here:
http://files.minecraftforge.net/maven/net/minecraftforge/forge/1.7.10-10.13.4.1614-1.7.10/forge-1.7.10-10.13.4.1614-1.7.10-installer-win.exe2. Run the install, click 'install server', click browse (...) button next to the path and put in the path you want the server installed to
3. Run the forge .jar file to generate the folder structure and files. I used a StartServer.bat file with the following:
java -Xms2048m -Xmx4096m -XX:PermSize=256m -jar forge-1.7.10-10.13.4.1614-1.7.10-universal.jar nogui
pause
4. Now you need to install the modpack via the twitch app. I assume you know how to do that. The reason you have to do this is that they didn't make a separate server files download for this modpack so you will have to do that yourself.
5. Navigate to the instance you created when installing the modpack. You can do that by right clicking the instance and clicking open folder within the app.
6. Now you have to follow the directions included in the modpack's page:
To Add Universal: Interdimensional Escape's Content to the Server, just Copy Over these Folders: config, mods, scripts (From Curse\Minecraft\Instances\Universal Interdimensional Escape)#
Go to the mods Folder, and Remove or Disable$ CustomMainMenu and ResourceLoader
7. If a world folder was generated during the previous run of the forge jar file, delete that. Now run the server and it should be operational. I made one while walking through these steps so you can play on it instead if you like.
Don't forget to edit the eula.txt file to true or the server won't run. It's a good idea to disable spawn protection as well.
My server is at netizenllcs.com:21002
