Fabian,I cannot find an account for you that is not a trial account. The only reason that you can post in this forum is because it is the general .NET area. You must have an active subscription to be able to access the forum. In fact, this forum area was supposed to be set this way as well (which has been fixed).
There are other forum posts regarding this, but the DDT does not support NULL data within a Deployment Data package.
If you do have an active subscription, then please email me at support@strataframe.net and I will move your forum account over to that active subscription. Sorry for any trouble.
