Hi All, if someone could give us some advice we would be very gratefull.
We really don't see the solution to this problem. If someone could look at the pdf attached and try to find out what goes wrong ? We really checked all code many times but now we are desparate. (Open the doc and click on the grey signature to see the errormessage). The byteranges are OK so it must be something else... Thanks so much already ...
