Nurflugel program problems

[Aerowerx]

The one created by Frank Ranis, I mean.

I have both the original German and the English translation by G. Gueville.

I have been just playing around with them.

The German version pops up an error message when I try to set a rib station. The error message is on the order of:

'y in m' ist kein gultiger Gleitkommawert

Sometimes there is a number at the front.

The English version just crashes with no message.

Any clues?
