Doesn't Work – AirNav Review

I have used the AirNav web site for several years and it works great. Like the last Review of the previous version, it only shows Thailand airports and requests $1 to feed the hungry, but gives no details or wants you to download the pay version. From previous reviews, the pay version doesn't work either. Not even sure if this version is truly the same AirNav.
