i am moving MIRC to a new computer and updraging

i mived the MIRC files ( i saw nothing in appdata roaming in win 7)
i am going to win 10

1- The highlight has been moved to address book.
do i have to manually enter every songle person in there as well as color ?
if so this is terrible

2- i used to auto connect ( i had to add the server seemed u didnt migrate it)
i cant now

3- i want the mirc chat in a separate windows.
i have to click on "desktop" every time it seems
isnt there a setting for this ????

4- can i just more the license from the old machine registry ?
i see 5 digits , dash and then seven digits
i also see a username

when was highlight changed ? it was easier the old way
