DMDE Express; Need help w/registering & changing background

[RolandJS]

Hey Guys!
I purchased DMDE Express version for 3 computers license package.
I'm having lots of trouble getting my desktop and two laptops recognized, registered by DMDE.
My eyes are bad enough that I cannot readily see the DOS-version menu board, do not know to activate their top menu bar.

** Does anyone know how I can change the DMDE dos-version's green background to white background?
And, what "hot-keys" combination will access its top menu bar? **

** Can somebody walk me through getting DMDE Express recognized and registered? **

I did several steps for my desktop, and now, I'm back to Free Version instead of Express Version.
If it's easier via email, PM me, and I'll give youse guys my email address.

[Mods: I posted the above in another thread, however, that thread title does not indicate my new questions
about DMDE, that's why I need to post a new thread about DMDE.]

F10

jermy, thanks! DMDE tech support also sent a quick-color guide for changing green to white. You addressed the F10 key solution, thanks for that hint also I'll post back results of my "hacking" the ini file.
I hope the process of DMDE recognition and registration goes smoother in the near future for all 3 computers.
[Will be updating you all about that also.]

Forgot to post back, until now. DMDE registered on two computers!
