NOTICE: Personal Point of View. I have and have used 5 different Christmas light control programs including Light-O-Rama, Spectrum, Aurora, Vixen and Light Show Pro and each has it's good points and bad points. With the exception of Light-O-Rama software the rest were written by software writers who enjoyed doing christmas displays and thought they could build a better program that what was out there. In some cases they succeeded in others they fell short but in every case they person doing the program had a day job to pay the bills and was just looking to maybe break even with there project. Does this mean that when we spend our hard earned money on there software we shouldn't expect a lot? No, but we should also realize that we are dealing with (in most cases) a company of one and they try to answer as many emails as they can and take care of there customers but they often fall a bit short in customer service. So you as a individual must decide if you like the features of a particular piece of software enough to invest your money into it know that it may have a few bugs that the developer is still working on and live with those until and update is released. In my personal case I used Light Show Pro 2.0 to program my show last year and ended up have to use X-Lights (a great program) to run the show due to problems with LSP's show player. David (creator of LSP) did his best to release updates and fix as many major problems as he could and is currently in the process of rewriting much of the software to better utilize system resources and provide a better experience for the user plus a couple new features. LSP has been my personal choice but it may not be yours that is what you have to decide for yourself and with the problems you have had with the demo I know that can be frustrating but hang in there, it make take david awhile to get to you but he will.
