Managed to manually remove A350 folders and did reinstall inimanager and everything works again
Try to load 1000-variant first and if it loads shut the sim down, restart and try to load 900 again, this way i got it working
Try this for the uninstall-issue, i managed to fix it. Also try to load -1000 first and see if it loads. If 1000 loads try then 900. At least i got it working that way
