Hi Tim and Jeff. Thank you for your answer. Plan G is installed on a stand alone PC using XP sp 2-3. Both FS9 and FSX are installed on the same drive. Plan G is installed in a folder called Plan-G on the c- drive not in programs files. All files for data about airports and navaids are in default locations that are supposed to be read automatically by plan-g. I went to the log text and I noticed errors. It seems that plan g cannot read the airports and the navaids when running build database. Everything else seems to work properly when build database is run. I will try to go to options and tell again where are the files for FS and scenery.cfg. If it does not work I will send you copy of the log.txt. In the meantime accept my thanks and my best wishes.
