Model: Custom built.
Operating System: Windows 10 1903
CPU: Intel Core i5-6400 CPU @ 2.7 GHz
Video Card: Nvidia GeForce GTX 1080 Ti
Vassal version: 3.2.17
Java version: Version 8, Update 221
Vassal modules: Space Empires 4x v. 3.0.1, Talon v 1.3 + Talon 1000 v1.1
If Vassal is already installed and the module is already in Vassal’s list, try running Vassal and selecting the module or double-clicking the module itself from a directory. Sometimes it will load, sometimes it will not. Usually, it doesn’t. Sometimes I can get it to work again by uninstalling the module or vassal itself and reinstalling, although this too is not reliable.
