Help with Silverfast SE S/w!!!

[jmg_MacOSXXI]

I have a Mac G4. I KNOW that UMAX did not provide drivers for OS X for the Astra 6450.

THis is my ISSUE and perhaps my disappointment.

I purchased Sliverfast SE 6
BUT it will NOT recognize my scanner as being connected to my MAC.
It is connected via firewire to a CD burner. I attached it directly to the G4 and still nothing.
version E-6.10r1

THIS is where I may be disappointed:
I downloaded version E-6.10r7
And this one did =D
=(
My REGISTRATION NUMBER that is on the case is NOT recognize by this version.

SO, please help me, is the r1 NOT what is going to work for me?
Why was there no option of PURCHASING the r7 version?
I HAVE to pay an additional $20 to ge the correct version?

PLEASE ADVISE!!!

PS I emailed in mid December and have not heard back

PSS I am trying to re-trace my steps, how did I get stuck with a CD and not the latest version being sent to me =/, please help..
