upgrading rules

[oncall]

OK, guys, this is tricky.

I have purchased two valid Hoster licenses. I was using on home PC and laptop and then other license on laptop. My dilemma, first laptop window crashed, ouch, reload windows all info gone, even changed name of that laptop. 2nd Laptop i am giving to son going to college and upgrading my own. I am trying to reinstall my 3.3xx versions ok, seems to be getting figured out. I purchased 4.0x version, today went to upgrade one of my laptops to 4.03,,,,,,,nope won't let me says been used elsewhere - but that is not true. How do i get help on this or whom should i be talking to.

Also, for purchasing a new laptop, is 4.03 running well enough on vista that i could purchase new laptop w vista or shoud i buy the xp software for $300 and roll vista laptop back??

Thanks,
