The library won't go anywhere. You could download the demo and use that until you get the box.
Right, I was going to suggest the same idea... The [a href=\"http://snipurl.com/LR1demo]"tryout" version[/url] and the official 1.0 release are the same software, I believe.
So you could download the demo to work for 30 days and then enter the serial number off the box when you finally receive it to make it permanent. I haven't done this myself (I just got the tryout and bought from there), but I have heard it working for others, given the delays in getting a boxed copy.
