I had to re-compile recently a module that was developped for our company by another company long ago. However I don’t understand how it has to be signed (i want to self-sign it) so I added the line “wrapper.java.additional.10=-Dignition.allowunsignedmodules=true” in the ignition.conf as mentionned here : [Allowing unsigned modules](http://forum.inductiveautomation.com/t/allowing-unsigned-modules/14304/2)  
My module is in Trial mode, does this mean I have to sign it for it to be Activated ?
