I've tried again several times. Despite rebuilding the shortcut to run MO with F4SE, it still won't run. I click on the icon, and I get the MO splash screen, then the command box for F4SE opens, and then it hangs. I've verified F4SE will load Fallout just fine. But it always hangs when I run the MO starter. Edit: I also just tried running F4SE from within MO, without using the shortcut. Just in case the shortcut creator was messed up. Same issue. The F4SE window appears, the cursor inside flashes, and nothing else happens.
