For what it's worth, I upgraded to v5.5 on the
first weekend it was available. That was when the website was able to take
money, but not provide access to download. I called on Monday to get the
appropriate UID and password to download. Did that, and discovered that the sn
only unlocked Polaroid AI and not HDR. I called back again and emphatically
stated that I expected my upgrade to cover both, given that I had bought both
as a package. (I bought my SS4k before the bundle.) I was given an HDR serial
no. So, I received both versions for $45.
Lasersoft's software might be great, though it
can be buggy. But the company and its policies are anal. I've gone through
hell trying to get each version to work. It took me a month to get a vailid sn
from them after I first bought the software for $300. Still can't use 5.5 with
PCI 5.0 installed. I had to revert to PCI 4.5. I encourage all Sprintscan 4000
owners to raise hell and NOT pay $90 for this upgrade.
