Just upgraded my home computer to Windows 7 Ultimate and have loaded all my Magenta software for FSX ok, but when I install Whazzup it just brings up the Introductory page and goes no further. I need to run Whazzup to convert my DEM to DE1 files. I have put a ticket in to PM but no reply, which seems to be pretty commonplace of late. Has anyone else had this problem getting Whazzup to run ?...Regards............Brian W.
