Wurm wont start after Maintenance Restart!

[Redock 2]

Hello There. I am running windows 8.1 Java 8 U45 64 bit.

Never had any Problems before.

 

Right after Maintenance Server downtime the client wont start anymore!

(its german and means "application cannot be started")

 

 

The startfile tab on "details" contains:
