This time, it's FL Companion not working. I click on it and it just does not do anything, apart from the few seconds of mouse pointer making the, ermm, waiting symbol. Used to be like that before, but usually opens up after 10 or so seconds.
Tried deleting the registry files associated with Wizou, reinstalling, and mostly everything that I could. So yeah, HALP PLSU.
So, myself and Rebirth kinda worked together and got it working Thanks to him.
The problem seems to be my Crossfire installation overlapping the Vanilla files, as apparently, the FLComp needs Vanilla files untouched by Crossfire mod files for working.
