Hey JKai, I am from Hawaii also. If you need help with myDMX Jingles is the best person to talk to about it, after all he is the myDMX tech support for American DJ. But if you need help either post on this forum or you can contact me on facebook. I have had myDMX for several years and have learned a lot of ins and out from Jingles, others and myself. Again so if you need help just feel free to ask.
Also the laptops I have run myDMX on is a Dell Inspiron with Vista 32bit - 3g ram, Acer Aspire 5672wlmi XP 32bit - 2g ram, Toshiba, All work really well(especially after I got the bugs out on the dell). But I prefer the Acer over the rest because I have never had issues running it on the Acer.
Though when you get your myDMX make sure you boot the laptop first then plug in the dongle then load the myDMX program. - As Chris Pickett always says. Because that is the most stable and correct start-up procedure for myDMX. Oh and turn off all the background programs and wifi myDMX likes to be the important only program.
