I have been using my Profilux 3 ex with the Profilux controls software on my Mac for years now. I use Parallels as my PC emulator and really never had much problems with it . Recently I noticed that the Profilux would disconnect soon after I connected . Within a few minutes it would just disconnect. I noticed that I was still using 5.1.4 so I thought I would upgrade to eliminate this problem. When The Profilux finishes installing the 5.1.4 software i get an error message saying "The ordinal 254 couldnot be located in the dynamic link library msi.dll. After I hit OK I get another error message saying "The procedure entry point could not be located in the dynamic link library KERNELS32.dll ". I tried removing the software the reinstalling again but still get the same message. I even tried going back to 5.1.4 but I get the same error messages. Have I forgotten a step somewhere ??? Any help I appreciated. The Profilux is connect to a router with a lan cable and my computer is using wireless connection. This has been the way I have had it setup since before I upgraded to the PIII . Thanks in advance, Neil
