The software date is 12/16/2009 and was installed from the disc directly to the comp. The computer is an Acer, using Windows 7 as the OS The processor is 2.2 ghz Intel Dual Core and 3 gigs of RAM. We are using mostly XLR cable, as well as an Elation Optobranch. We have 4 X Move LED Plus's and 8 Venue Par56 cans running through 4 seperate chains into the opto split which is then going into the controller box which goes to the comp. When trying to set up the cans instead of the movers through the ScanLibrary, the cans were unresponsive and the movers were acting on their own. I am going to try to install the movers again and see if it acts the same as last time. Thanks again!
