Import of 2009 SP1 Objects into Dynamics NAV 4.00 SP3 --> When "Design" Client crashes


i have imported Objects programmed and compiled NAV 2009 SP1. This Objects are not very special. The import into Dynamics NAV 4.00 SP3 worked, but when clicking “Design” on one of these objects, the client crashes.

Any idea, how to make these objects work in NAV 4.00?

Export them as text, and in a text editor remove all the Nav 2009 features then import the text back in to 4xx


thanks, it worked!
