Just decided to start modding Fallout New Vegas and when I activated the game on Vortex I got an error from the script extender installer. It says that it is unable to download/install script extender. When i click on more it says installed version: undefined. Not sure what is wrong, its a brand new install of FNV and just activated it on vortex for the first time.


these are the details of the error

This will be fixed in the upcoming 1.3.9 release, for now please install the Script Extender from here https://github.com/xNVSE/NVSE/releases


Then drag and drop the 7z archive into the "drop zone" at the bottom of the mods tab.
