You won't regret it.. Its a great addon and there is a second update/enhancement coming out in June.

They have always answered quickly for me as well. In fact they keep you well informed on future updates that they are working on. Try using a different email account, if you don't get a reply from them. I use hotmail and it works fine with them.I run their scenery with Bill Lyons Golden Hawaii and have absolutely no problems. I used to have a multitude of scenery upgrades installed for Hawaii, but did away with them for GH... It was never a problem with the 314.
