EccoPro user moving to Windows 7

I use EccoPro to manage all sorts of information.  Now I need to move 
from a windows XP computer to a Windows 7 computer.  (Windows7 
Professional, 32-bit on a Dell desktop computer, and 64-bit on a 
Toshiba laptop computer.)

When I go to  http://www.compusol.org/ecco/   I see that I can pay a 
reasonable membership fee and just download a new version of Ecco 
Pro, designed for Windows seven.  It is "much improved" with all 
sorts of additional features.
"Compared to the Standard Installer Version 4.0.1.363 you will find a 
vast improved Information Manager which brings together your 
contacts, calendar, appointments, tasks and projects in one 
integrated application."
What I want is something that will function the way my current 
version 4.01 functions. Basically, I need the notepads and columns, 
the ability to sort and filter.  I need something that will open the 
many .eco files I have already created, that have so much data stored in them.

When I look at the graphic, it seems that the new Ecco has many 
windows for different functions.  Will I be able to get rid of those 
windows and go back to the look I'm used to?  I realize there may be 
some new features that would benefit me, but my top priority now is 
to get myself functional on the new computer ... I can't spare the 
time to learn any new features.

I still have the Setup32.exe file dated  05/08/2004 6,721,202 bytes.

It looks like I have three choices:  I could learn how to install 
setup32.exe under Windows 7, OR I could download
EccoPro from Compusol, OR I could download "the tested and stable 
EccoProX Installation" from Compusol.

I am hoping someone can advise me the simplest, most reliable way to 
get my current eco files readable and usable on a Windows 7 
computer.  If I download EccoProX, is there a way to make it look and 
feel like my current version of Ecco Pro?  Will it read my current files?

Many thanks!
