Installation

[satvu]

Ok, Here's the deal. My computer crashed. Got another computer. Went thru all the formatting, reinstallation of programs, etc. Then I try to install Microstudio for the plexwriter premium external cdg drive (purchased from you) and get the message that this was previously installed on the other computer.

Ok, I have an older version of Microstudio, installed that but it won't recognise the external drive.
Ive purchased the program twice from you.
How do I get it installed?
