Just bought the FS Genisis American Roads/Rivers/Data...and took off from my home airport, KDET, and went out serching for the biggest road in Detroit...and guess what, it wasn't there! >:(
And furthermore, 'Lakeshore Dr.' was 3 miles inland
While I can see how you feel, did you search and read the forums they have, and asked if these roads were accurately shown? I know you probably thought they would be there but I personally wait a few months and then read feedback on payware and freeware products.
I have had that scenery addition for quite a while....... and have found all the roads aroud here............. including the tiny, TINY ones are right where thay should be. This was a far, FAR case from the default MS roads and rivers and railways.
Are you SURE that your install worked? It should be a VERY obvious change to the default scenery.
I'd suggest that you check out the American Roads info on the FSGenesis forums to try to figure out what your issues are. I fould the install simple and it worked great first time. I have also added the "Roads Repaver" from the FSGenisis site. That too works great on my system.
I wonder if they currently have a corupt file on their download server?
