Hi Arista,Thank you for your prompt reply.The installation seems to have progressed a little further now stopping at TileAPI : Mapversion `55`The Tileproxy Photoreal World directory in drive C: comprises directories LWM plus directories 0000 to 1107 each of which contains scenery and texture directories . All of the scenery directories seem to contain bgl's but many of the texture directories appear to be blank. The scenery.cfg in FS9 appears to in order with correct references to the directories 0000 to 1107.The problem appears to be in the proxyUSer.ini configuration which I have set up as follows: #source=Acme Globe Service //(Fake Example)source=Service Example 1 #source=Service Example 2 //(Google Earth)#source=Service Example 3 //(Yahoo Maps)#source=Service Example 4 //(Ask.com)[service Example 1]cache_folder=E:Tileproxy Cachecache.service1network_module=libnettilemodule_config="conn=20|rate=2.0|verbose=0|server=http://a*.virtual earth|path=/tiles/a%s.jpeg?g=%v|quad=0123|balance=0123|useragent=Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; SLCC1; .NET CLR 2.0.50727; .NET CLR 3.0.04506; .NET CLR 1.1.4322)"min_level=9max_level=17map_version=55level_mapping=9,10,11,12,14,14,15,16,17#level_mapping=9,10,11,14,14,14,15,16,17color_hack=Yescolor_level=13bulk_extend=50I would appreciate any help that you may be able to provide.Regards,Alan
