Suddenly game won't run.

[Killswitch]

When trying to launch the game today - either from an Amber client or from the website it simply won't launch at all (nothing happens). Tried reinstalling Java to no avail. When tried to run the Amber client as administrator i get the following error: "Unable to access jarfile hafen.jar" even though it is in place. Any ideas? Thanks in advance.

Seen this a bunch recently, think they did a Java update that broke it for a lot of people. Your class path is likely messed up and windows doesn't know how to open Java files anymore. If you tried a reinstall, try looking into fixing your class path, Google has guides. Easy way to check if this is your problem is to just type Java in a command prompt, you should get Java related options back.
