HI All, I hav been using ASV 5 for some time now without any problems. Today i decided to install the 512 cloud sets. All went well and i loaded my aircraft and was ready to go when i got a box pop up stating the following.Buffer overrun!!!It gave the the file as "microsoft games/flight simulator 9/ fs9.exe"It then said the the buffer overrun has corrupted the programs internal state and fs2004 crashed to desktop. I have tried and tried again with and without ASV to start my flight and everytime this happened and everytime it crashes back to desktop.Can anyone help please. My pax's are waiting to get home lolregardsDal

Hi,This is a strange one. Try going back to the 256 clouds. Also, what are your system specs? Have you updated to B367?Hope this helps,JimActiveSky Sales and Supporthttp://www.hifisim.com/images/asv_dev_team.jpg http://www.hifisim.com/images/asv_proud_supporter.jpg
