FSinn messed up

Last night, I installed FSinn on my primary FS computer to get the Euroscope Towerview working.Just a couple of hours ago, I wanted to fly a bit around in a newly downloaded aircraft, listening in on the FSX ATC to be aware of all the fun AI traffic around me.I discovered both the FSX ATC window and the Briefing window (Shift + F10) have completely lost it.The text in the ATC window is not readable (if it shows up in the first place) and both the ATC window and the briefing window are way smaller then the white lines that become visible if you try to replace/resize the windows.I uninstalled FSinn and FScopilot, but no result, it stays this way.Does anyone know a solution for this problem besides completely reinstalling FSX?Reinstalling would be an absolute last resort, since it would include reinstalling various add-ons (both airports and planes), a lot of WorldOfAI traffic and redoing some tweaks I did in the past.I know for sure the problem started after installing FSinn, since I did a short flight yesterday without problems, before I installed FSinn.
