So, i did everything recommended in this thread... updated to Jave 1.7, its the 64bit Version for my 64bit OS, it's the only Java version enabled, the Path Variable is set to the jre7 version, restarted several times, downloaded the server again, in case config files may have been changed when starting with errors...
But still exactly the same error stream, posted here before by many others...
Any other ideas?
