I'm having the same problem. It installed fine, but when trying to run, it asks for registration. I tried to enter my Ultimate OD key which is valid until March 2010 and it said the key was not valid. Looks like some other people here have had the same issue. I'll keep monitoring this thread for a fix.
Same problem here , update installed fine but it's asking for email/registration.
I'm also good till March 2010
------Update------
OK, I think I fixed the problem:
In Impulse right click on IconPackager and view registration,
copy registration # to clipboard.
Now right click on IconPackager again and choose "run" (you should get the registration window)
Enter your email and paste your reg # into the appropriate fields and click Activate.
IconPackager should startup right-away 
Worked for me....
