Package Building stops with "Cooking Error 25"

Im not able to build my Game for Windows 64-bit, because of Cooking Error 25. I installed all requirements, like the VS2015 C++ plugin, and the Editor symbols for Debugging, altough im coding in Blueprint. I had Error 5, but then i uninstalled all Plugins, and now I get Error 25. I am using UE4 Version 14.3. Here is my Output Log: [link text][1]

Could i just delete T:\UE4,14\UE_4.14\Engine\Programs\AutomationTool\Saved\Cook-2017.02.20-22.48.53.txt ?

Check to see if you have the same trouble packaging a blank template. Please also delete your Intermediate and Saved folders from your project. Try and package again, upload any new logs.

Looking forward to hearing back from you, thanks!

Hey ,

We have not heard back from you in a few days, so we are marking this post as Resolved for tracking purposes. If you are still experiencing the issue you reported, please respond to this message with additional information and we will offer further assistance.

Thank you!

Ok this reply came a bit late, but deleting the Saved and Intermediate Folders completely destroyed the Project. I have a new Question by the way, so i think, ill close this question now.
And i tried Packaging a blank Project, didnt work.
