I just got mine too. Copy and paste the serial and reg numbers with no problem.
You have to be careful when you copy that you don't get a leading or trailing space.
I just tried it on the 2 buss and it glues the mix in a nice way. I know it isn't normally
used like that but I tried and was pleasantly surprised. I kept clicking and unclicking the bypass button to compare with and without and always liked it better with it on. Only set for about 2 db of compression. Seems to add life, or maybe seems to animate the mix.
