Tbh… I’m not really following you here. JME2_2011_07_15.zip is that a typo or is it in fact jME2 ?
I am using the nightly builds of jME3 from within the IDE. I am not retrieving any files manually. Where or how can I locate the above mentioned zip-file? I have done a search on my entire drive for this file and it is nowhere to be found.
