Not knowing any better I used 2.5.0.7, The issue that i came across was scheduler, it worked some nights and other i was frustrated. I could get it running by restarting current timer, but it would not start the next time show. I kind of gave up and just went along with the program. What I had to do is recreate the manage settings and reset the scheduler. But that worked for a couple of nights. So i thought of purchasing Light Show PRO (LSP). Will see!!!
I am going to wait for Vixen 3.0 to come out, and then compare, test and retest. i would like to have a good show in 2010 without software issues.
