After the problems with Appforge, we found a way to get around it and make the PDA version working again.  Even better, the client does not need any registration anymore :-)

Since this is a 'non Appforge' solution I can not take any responsebility for it, but on all my test devices it works well. It also means I was able to create the Filmcalculator for PDA for all versions with the same and latest programming language and wil be able to update them all again.
All PDA files have version 5.0 numbers to reflect the new version update.

Please report back in the forum or by email how it works for you.
