I am made a new release in which all assemblies are signed.

Just copy it to the server manually, and then specify the path to tesseract.dll as described here: http://forum.patagames.com/posts/t14-Unable-to-load-DLL--tesseract-dll

The Create() method shows a nag-screen sometimes. You saw it in your developer environment when develop the app I guess. The nag-screen is shown in trial mode only. tesstrial.png (28kb) downloaded 575 time(s).
