HOSTER GONE did i do somethig wrong

[northlander]

Hi douglass
I have pentium 4 2.4 GHz 1.00 GB of RAM
wINDOWS xp on the shuttle by mtu
what happens when i click on 3321 to install and goes to second screen
this is what it says
click yes to remove the current version to allow installing new version .Only the program exe comp0nents and folders created when first installed will be removed. kma wav bin or other files imported created etc and your preferences saved while running the program will not be removed If upgrading to a new version run the setup program again to finish installing.when your click yes to install what happens it takes my 3320 out
like it should to allow installation, then when you click on 3321 again to install it will not
i then tried to install 3320 and 3319 upgrade but that version i bought on jan 30th which was 3319 and 3321 that i purchased march 29th will not install like i said i restored my computor and i got my 3320 back working fine,i don,t know weather i had to buy 3321 or not or if this was a free upgrade. I believe its something minor i phoned mtu and sent them a ticket .
thanks douglass you might have some ideas
