Autogen and photo scenery

Using the new tools i managed to produce a nice ground texture and watermask, but I am stumped by the annotator tool. in FS9 i could annotate each individual texture, but now it's all lumped into a single bgl, no textures to annotate... i tried adding autogen by opening the BGL in Annotator and i was surprised to see my entire texture show up. I fiddled around with the settings of the annotator (very confusing) and placed a few building and a few trees. FSX crashed everytime... so, is anyone having luck doing what im trying to do? the SDK is very vague on this and I'm starting to wonder if it has anything to do with my default.xml? (i may have overwritten the original back up) guidance please!
