Answer 1

If you can copy the whole exception it would be much more better, but once I faced with this Exception and this is because the function calling from your dll file which I guess is Aspose.dll hasn't been signed well. I think it would be the possible duplicate of this

FYI, in order to find out if your dll hasn't been signed well you should right-click on that and go to the signiture and it will tell you if it has been electronically signed well or not.
