I bought TFD and am having an issue when playing NOD, after I have set up lasers. Once they start working their magic on GDI I will get a lockup and loop of sound, but only when lasers are firing. So, I want to replace the laser sound with something else, and have downloaded the editor etc.. but don't quite know how to replace the laser sound with another sound available in the game (electrocution would work ok). Any help?
