i recently joined a virtual airline. it required you to download fsuipc4 and vasf 4 i did that and followed the directions. no problem, everything worked great for about three days and then on a flight of about an hour just before landing everthing freezes up and a message says im out of memory. it shuts fsx down , so i turn off cp and reboot and restart fsx. then i click on vafs and it says it has stopped working and after uninstalls and reinstalls of vafs and fsuipc4 (probably a dozen times each) i get the same results that vafs has stopped working and in a little window it says windows is searching for a solution. windows is still searching but does anyone have any ideas?
