I don't know this particular campaign. Look for instructions in the download for adding new entries to Airbases.dat. These can be copied/pasted direct from the text file to avoid mistakes. There could be a sample Airbases.dat included. Missing or incorrect Airbases.dat entries is the usual cause of your problem.

Of course, it's possible the author of the campaign doesn't know about this.

Thanks for the quick response to the querrie.
yes i use version two and yes i did a reinstall and was more careful with the updating of the reinstalled cfs2. everything okay now  works well.
thanks for the tips.
