Oh well. I did notice the thread was a little old.
I grabbed the RB 2005 r3 version anyway just to see what it was about.
Strange situation with that demo. You can enter any name in the registration box along with the code 12345678-12345678-12345678-12345678-DDDDDDDDD and it will extend your trial period to 2079.
You can edit the hex @ addr 00112B4h and replace 8A 80 A0 00 00 00 with B0 00 90 90 90 90. This will eliminate the nag screen.
But the compiled exe's still have a time limited lifespan. That could be easy enough to work out but...
To much trouble.
