Hi,I recently installed FSPS - FSX BOOSTER V4 but then I uninstalled it since my performance was worser then before.When I started up my FSX, it looks like i lost almost all of my trees, only a few are there.I already tried to rebuild my fsx.cfg file but still the trees are gone, I'm not looking forward to reinstall whole FSX again.After some research I found that it could be something with the default.xml file which should be located in the autogen folder but mine isn't there, so I guess I deleted it.How can I solve this?In the screenshot attached you can see what i mean.

If that file is missing, do a Repair install and the DVDs will put it back in place.

Okay thanks for the quick help Jim, is it safe to do the repair install without having to uninstall any add-ons?Regards,

Yes, but you may need to re-install them, especially if they are texture programs. Planes usually do not need to be re-installed.
