4.03 Update Question

[JamesHFaulhaber]

I purchased Hoster 4.02 a few weeks ago and have had the same frustrating Vista problems as other users.
So I downloaded what I think is your free upgrade to: Hoster 4.03
"Hoster 4.03 - To install and run requires purchasing Video Hoster 4.00 or an upgrade to get a Hoster 4 Registration Code."
I ran this free program and nothing changes with my version of Hoster 4.02
Do I need to purchase Hoster 4.03?
Or do I need to uninstall Hoster 4.02 and then run Hoster 4.03?
I am very new to computers and uninstalling Hoster 4.02 worries me that I may lose something.
How do I upgrade to Hoster 4.03 from Hoster 4.02? I do not see this question answered in your threads.......
Any help will be gratefully appreciated. Thanks so much for your forum and and wonderful Karaoke programs. I feel your pain with Vista! I'm sure you guys are more frustrated than I!
