Thanks for your help Shirley, very grateful for it.
It worked like a charm, but then when I tried to use one of the skins it came with, I lost half of my HDD, and was put in repeated restart mode. I then reinstalled Win XP Pro SP3, tried it again, with the same results...must be an SP3 issue.
Now I took the plunge and installed the Vista 64 Ultimate that my motherboard came with...and am now stuck in repeated "Reboot Now" mode, where I am told to shut off all spyware and firewalls. Reinstalled everything, shut windows defender, firewall off and didn't install AVG, and was still told to "Reboot Now".
Did I mention IconPackager installed perfectly on both OS's.
I guess I am destined to live without the Mysteria experience, although....this Aero Interface is easier on the eyes than Luna.
Now Impulse is telling me that there is a "Problem getting update data" (I hate change...when will it end)
