Can not model in VC 7.1 SP3

Hello,

after creating a model in the VC 7.1 SP3 the board is not shown. Instead I receive the following error message in the console:

[E] Failed to send signal to the board : 'elmBoard.boardObj.onsignal' ist Null oder kein Objekt

...

[E] Failed to layout shape(s): 'elmBoard.boardObj' ist Null oder kein Objekt

...

What do I have to do, to avoid this error?

Thank you in advance for any help,

Peter
