Just got around to opening and installing the four copies of PM4.2.1 I'v had on the shelf for a while. First copy: installed on WinXP Pro no issues. Second: install on Mac OSX Tiger no issues even through the upgrade download. Third: install on Mac OSX Tiger but when I try to enter the activation code I keep getting a error message that says the password is invalid. Fourth: installed ok to Mac OSX Tiger. I have four copies of the software. Any help would be wonderful.
Thanks...
