STILL TRYING!!Need ADMIN HELP PLEASE - hit 100 install limit;now reset

[Kobesdad]

I'm still trying to see what if anything will make the latest version of Hoster (4.5) work on my laptop with XP Pro.
Problem is that my registration has been locked for 4.X I do have 3.321a installed but can not upgrade.I submitted a support ticket on Oct. 3 and it's status is still not viewed.I understand it was the weekend (Fri.) so I thought I might get a response in the beggining of the week. I even called and left a message.I have seen new responses from ADMIN on the forum and thought maybe this is where my question would best be found.

Thanks in Advance.
