If you've got a mac you can run a program called incognito to block specific programs from registering on the network, I used to use it to stop softwindows from doing the same check in a lab of 20 machines, we bought 20 copies, but over the years lost the codes. Works a treat, you just run the software on one box after it's registered then you select the ID you require, and block it, copy the config file to the rest of you machine, and you're set. later jb
