AdManager Plus won't start after Update to 6.3

AdManager Plus won't start after Update to 6.3

I've installed the update 6.3 for Build Numbers  6200 through 6292 (see:  https://www.manageengine.com/products/ad-manager/service-pack.html)  yesterday. I've installed the Update like mentioned here:

When the update was finished, I tried to restart the server:
- Start Service "ManageEngine ADManager Plus"
- Execute StartDB.bat

When i try to open the webpage I get an error "The page can't be displayed. If we try to start the Server as an application( Start → All Programs → ADManager Plus    Start ADManager Plus) we get this Error:



Running the "run.bat" script results in the same error. Can anyone help me solving this problem ?

Thanks !
