Hi headscratcher,
Firstly I like to compliment you for trying and I do hope that when (and if) I am 77 I still have the stamina you have.
Dreamlinux is indeed -- IMHO -- not as beginner friendly as for example Ubuntu and has its own target group.
Should you ever want to try it again or like to know more, feel free to drop in and ask questions.
We'll be here and will try to help you where we can.
With regard to VirtualBox or VMware Server, you may find these blog posts interesting to read (not intended as shameless self promotion btw

).
And if you have questions on other distros then Dreamlinux ... as you know you can ask these always at the LxH forums.
