In attach my logs.
So what happened? I had 1.2.16 on that PC, I installed previously the openbeta and uninstalled it. Yesterday I installed the Openbeta again, it updated to the latest version 1.5.2.48162.
I go to the module management and choose the A-10C and FC3 to install. It starts installing those, but I immediately notice it only seems to copy the A-10C files from my 1.2.16 install. Once in 1.5.2.48162, the FC3 module is NOT installed and doesn't any longer appear in the Modules list. I still have sufficient activations.
Now that it isn't even in the Modules list, I'm stuck.
What is the command line method? Logs.zip
