I had a long string of success in downloading unpacking (with winzip) and using plug ins. However, the last few times have been problematic, and I do not know why. Just now I had problems with a demo version of Brainworx BX-XL. The program appeared to install o.k., I restarted the computer as suggested, but when I load the plug in, a page comes up (as expected) saying do you want to continue using BX-XL trial version, click trial to continue, after which a window opens up that is nothing like what the BX program looks like, and it is a dead window, with no features. I tried moving the .dll file around, but this did not seem to help. The BX-XL plug also shows up in my list of plug ins, but it simply does not work. Any guesses what the problem might be?
