Problem: When trying to compile adventures I get a "Your flight plan had errors in it, Please contact AETI" voice message!
Solution: The problem stems from the version of ALPC that is currently loaded and the settings it has setup. In order to fix the problem you need to do the following:
1) Make sure to install the APLC32 version that comes on the ProFlight 2000 CD. If you have an older version it will give you a compile error.
2) Once you have verified that the correct APLC version is installed you need to setup. Check the APLC settings to verify the program is set up properly. Under your windows START, go to PROGRAMS; then to APLC32, then to options. The following two buttons should be checked:
"copy adventures back to current directory"
"version output for latest installed version"
If this setting doesn't work then change the second option to:
"output adventures to FS2000"
Make sure no other options are checked. Click 'OK' and then recompile your adventure!
Das sollte eigentlich helfen, was auch immer gut ist, ist hier mal die "Suchen"-Funktion zu bemühen

gib dort mal "PF2000" oder "Proflight" ein.
